patch IDEA 3 to work with jdk 1.4.1-p3

[Felix von Delius]

Here's a brief hint how IntelliJ IDEA 3.0.3 can be patched to work on
FreeBSD:

After installation, IntelliJ IDEA 3.0.3 complains about not running on
"1.4.1_O2" (the linux-jdk crashes). The problem is that the great
FreeBSD Java 1.4.1 patchset 3 does have "1.4.1-p3" instead of
"1.4.1_O2" in the java.version system property.

The patch is easy: just patch the file
${IDEA_HOME}/lib/idea.jar: Inside there is the file
com/intellij/idea/Main.class where the string "1.4.1_O2" has to be
replaced by "1.4.1-p3".

I did it by unpacking idea.jar, patching the Main.class file (with
Emacs hexl-mode) and building a new jar, but since the jar is
uncompressed, it should be possible to patch it with any hex-editor
(Emacs is not too fast in hexl-mode for long files).

IDEA works great, but debugging seems to be a problem.

btw: does debugging work with other IDEs (Eclipse?) or is it a problem
of the jdk14 port?

cheers,
 Felix
