Red Hat Bugzilla – Bug 38249
JDK1.3 and JDK1.3..0_2 will not run
Last modified: 2008-05-01 11:38:00 EDT
Sun's and Blackdown's java from jdk1.3 and jdk1.3.0_2 (Sun only) hang the
terminal. First, I had to place the libjvm.so (from
jdk_inst_dir/jre/lib/i386/client/) into /usr/lib. Then I ran java -
version from jdk_inst_dir/bin and the term just sits there. A ps shows no
activity to the associated java processes. JDK1.2 seems to run fine.
I think this might be a good time to put in a plug from having Red Hat
include a good reference java rather than that quassi knock-off called
kaffe. Come on guys! You can package the jre in the distro not to
mention Blackdown's implementation.
I can confirm that this is a problem. I'm going to have to downgrade because
of this problem.

Um, no we can't ship any JDK/JRE environments. The licenses prohibit
them, and they aren't open source anyway.
Did you try setting LD_ASSUME_KERNEL as specified in the release notes?
Here are the results.
% export LD_ASSUME_KERNEL=1
/bin/sh: error while loading shared libraries: libdl.so.2: cannot load shared
object file: No such file or directory
You should use
It is written in RELEASE-NOTES btw.
export LD_ASSUME_KERNEL=2.2.5 does indeed work around this problem.
What side-effects might this have on other things? Are the release notes
The effect of LD_ASSUME_KERNEL=2.2.5 is:
a) libc (libm, libpthread) no longer assume they run on kernel 2.4.1 and above
(the assumption means some optimizations)
b) libpthread cannot use %gs register based threads, they use the stack pointer
based fixed stack size threads
So basically it is mainly a performance issue, or if some threaded application
needs to use either smaller or larger stacks than 2MB (smaller so that it
can fit more threads into virtual memory).
