Hello-
On FreeBSD 5.4 i386, I've had problems with multiple threaded
applications under JDK 1.5.0, and have solved them using a patch and the
ports version of jdk15. This was discussed in May, 2005 on this mailing
list [1] and I am just confirming & documenting.
For anyone wishing to repeat this success, the steps are quite
simple:
* Get the jdk15 port, PORTREVISION=2 from cvsup or just from [2]
* I used jdk-1_5_0-src-scsl.zip & jdk-1_5_0-bin-scsl.zip from Sun [3]
* Get the eyesbeyond patch: I used Patchset 1 from Greg Lewis [4]
* Patch sources according to Arne Juul [1] [5]
* make install!
Thanks to Greg Lewis as always, and Arne Juul this time!
Have others had similar success? Should this get added to the port
by a committer? Or maybe Greg has this planned for patchset 2?
--Oliver.
