This document contains a brief list of the most important OS/2-specific changes
in the OpenJDK product from release to release.


CHANGES

1.6.0 Build 27 GA5 (2013-02-17)

  - Make sure RICHED32.DLL is used for java.awt.TextArea. This makes this class
    actually work. Affects many AWT applications.

  - Fix missing menu bars in AWT applications.

  - Fix broken file open dialogs in AWT applications that couldn't be dismissed
    and would not let navigate through directories.

  - Implement saving JPEG images through com.sun.image.codec.jpeg.JPEGImageEncoder.
    This fixes some old Java applications using this deprecated class.


1.6.0 Build 27 GA4 (2012-12-31)

  - Updated OpenJDK sources to b27 (released October 26, 2012). The list of
    changes in b26 and b27 is available here:
    and a number of other fixes. The full list of changes is located here:

  - Use stdout instead of stderr for printing usage info from java[w] launchers.



1.6.0 Build 25 GA3 (2012-07-21)

  - Updated OpenJDK sources to b25 (release May, 07, 2012). The main changes in
    b25 are the latest round of security updates (in jdk and corba repositories)
    and a number of other fixes. The full list of changes is located here:

  - Fix a hang in the TCP/IP Configuration application when saving the changes.

  - Fix warnings about stack guard pages that could eventually lead crash the
    Java application.

  - Add related changes to make the IcedTea-Web (Java) browser plugin work.

  - Fix a possible secondary crash when generating the Java crash report.

  - Change the version numbering scheme to 1.6.0_BB-bNN-name where BB is the
    upstream Build number, NN is the OS/2 sequential build number and name is
    a symbolic name of the release. This release's version is 1.6.0_25-b01-GA3.

  - Make sure the BEGINLIBPATH setting is not necessary for JAVA.EXE and
    JAVAW.EXE binaries (and for creating a JVM by loading JVM.DLL directly).
    It is only necessary for JAVAC.EXE and other SDK tools.



1.6.0 Build 24 GA2 (2012-03-19)

  - Updated OpenJDK sources to b24 (release November 2011). The main changes in
    b24 are the latest round of security updates (e.g. the security changes in
    jdk repo) and a few other fixes. For more information see the detailed list
    of all the changes in OpenJDK 6 B24 here:

    http://blogs.oracle.com/openjdk6releases/resource/OpenJDK6-B24-Changes.html

  - Make the JNI interface calling convention compatible with IBM Java. This
    allows old OS/2 JNI DLLs to be loaded by OpenJDK and makes standard
    programs like LVMGUI and TCP/IP Configuration work properly under it.

  - Fix hangs at crashes when the Java process is killed by Ctrl-C or by a kill
    signal.

  - Fix crashes following the "Attempt to protect stack guard pages failed"
    warning message (Odin bug).

  - Fix spontaneous NoClassDefFoundError exceptions thrown by some applicatinos
    at startup (Odin/b22 bug).


1.6.0 Build 22 GA (2011-06-27)

  - Fixed crashing of Java applications on SMP systems.

  - Don't allow to use two different JVM types at a time (as it is not possible
    due to OS/2 LX DLL format limitations) and give an error message instead.

  - A number of minor fixes in JVM and Odin libraries.


1.6.0 Build 22 WSE (2011-05-12)

  - Fixed: Opening the print dialog would crash the Java application.

  - Fixed: Printed text was flipped along the base line on output.

  - Fixed: The dtdbuilder tool would write the binary DTD to stdout causing
    "\n" to "\r\n" expansion on OS/2 and thus breaking the resulting file which
    in turn would completely break support of HTML text in Swing components
    [vendor bug, regresion Build 22 (RC2)].


1.6.0 Build 22 RC2 (2011-03-28)

  - Updated OpenJDK sources to b22 (release February 2011). The main changes in
    b22 are the latest round of security updates; in addition, there are a few
    copyright and licensing fixes. A detailed list of all the changes in b22 is
    available here:

    http://blogs.sun.com/darcy/resource/OpenJDK_6/openjdk6-b22-changes-summary.html.

  - Fixed and improved system tray support. Requires the Extended system tray
    widget for XCenter/eCenter (see README.OS2 for a download link).

  - Fixed: Sound did not work in LIBPATHSTRICT=T mode (Odin bug).

  - Fixed: SIGABRT that would unexcpectedly terminate some Java applications,
    e.g. IzPack based installers (GCC compiler bug).

  - Fixed: Crash during Drag'n'Drop operations in some Java applications, e.g.
    JAlbum (Odin bug).

  - Fixed DLL loading code in the JVM that would print a useless message when
    one of the required DLLs is not found.

  - A bunch of smaller fixes in Odin libraries that should improve OpenJDK
    behavior.


1.6.0 Build 19 RC (2011-02-21)

  - Ported and enabled the JPDA (Java Platform Debugger Architecture) component
    which provides a framework for debugging Java applications.

  - Added sound (audio and MIDI) support to Java applications using DART.

  - Added a free implementation of the com.sun.image.codec.jpeg package (taken
    from the IcedTea project) used by some old Java applications like Jeti/2.

  - Renamed all Java DLLs by adding a 'j' prefix to the names to avoid possible
    conflicts with system DLLs.

  - Fixed: Accessing the network from Java applications would crash on some
    machines (Odin bug).

  - Fixed: Spontaneous 100% CPU load in many Java applications (e.g. GenealogyJ
    Jeti/2) when throwing NullPointerException as a result of accessing null
    objects of some application classes (Odin bug).

  - Fixed: java.util.prefs.Preferences: Use the Open32 registry on OS/2 instead
    of throwing an exception.

  - Fixed: JVM used PATH instead of LIBPATH to comprise java.library.path
    resulting in inability to find JNI DLLs in some applications.

  - Fixed: Crash in java.io.WinNTFileSystem.getSpace() (Odin bug).

  - Fixed: Exception java.awt.image.ImagingOpException in many applications due
    to wrong exports from in jmlibimg.dll.


1.6.0 Build 19 Beta 2 (2011-01-12)

  - Added a predefined font configuration file to use the Liberation font family
    as Java system fonts (see README.OS2 for details).

  - Added the jawt.lib library to the SDK package.

  - Added some missing GUI and audio classes to rt.jar.

  - Fixed: Java could not find a .jar file in the current directory when
    starting it with 'java -jar filename.jar'.

  - Fixed: Non-ASCII characters in the title bar of any Java window would be
    drawn using wrong glyphs.

  - Fixed: Java could incorrectly detect the default object heap size on some
    systems for some specific VIRTUALADDRESS values and abort at startup with a
    "Could not reserve enough space for object heap" error message.

  - Fixed: java.io.File.mkdirs() wouild always fail which would in particular
    abort the installation process of some applications such as jEdit, iTrain
    (this bug was actually fixed in Odin).

  - Fixed: An attempt to use Drag & Drop in any Java application would cause
    a Java exception and program termination.


1.6.0 Build 19 Beta (2010-12-30)

  - Added support for AWT and Swing classes which brings GUI capabilities.

  - Lots of small fixes.


1.6.0 Build 19 Alpha (2010-10-01)

  - First public release.
