Description Chris Croswhite 2001-04-29 06:38:50 UTC

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?

Comment 3 Rob Lembree 2001-04-30 04:30:47 UTC

Here are the results.

% export LD_ASSUME_KERNEL=1
% /Work/jdk1.3/bin/java
/bin/sh: error while loading shared libraries: libdl.so.2: cannot load shared
object file: No such file or directory

Comment 4 Jakub Jelinek 2001-04-30 07:38:29 UTC

You should use
export LD_ASSUME_KERNEL=2.2.5
It is written in RELEASE-NOTES btw.

Comment 5 Rob Lembree 2001-04-30 17:45:26 UTC

 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
available online?

Comment 6 Jakub Jelinek 2001-04-30 18:03:49 UTC

ftp://ftp.redhat.com/redhat/linux/7.1/en/os/i386/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).
