Description mmeeks 2004-11-29 05:50:43 UTC
So; my fails with:

[Java framework] The JRE specified by the bootstrap variable UNO_JAVA_JFW_JREHOME
  or  UNO_JAVA_JFW_ENV_JREHOME could not be recognized. Check the values and
make sure that you use a plug-in library that can recognize that JRE.

This is particularly painful.

It appeared this warning could be reproduced reliably by just running 'javaldx';
however having run 'strace' on javaldx it now works 100% of the time. Either
there is some shared state somewhere - or this is nastily broken.

Of course - the OSL API is nastily broken on Unix, since it doesn't hide EINTR
from you still [why!?]. Perhaps this:

--- jvmfwk/plugins/sunmajor/pluginlib/util.cxx

+                       case osl_File_E_INTR:
+                               continue;
                 return RESULT_ERROR;

Would help - although, I can't verify that.

s/shared state/stored state/, & I guess the EINTR thing is rather a shot in the
dark, hopefully there is some more sensible/simple explanation.
Comment 2 kay.ramme 2004-11-29 09:25:16 UTC
Michael, taking a look into sal/osl/unx/signal.c shows, that it sets SA_RESTART
for signals which we actively handle, but not for signals we don't handle
(SIG_IGN). So, if you may give the following a shot:

sal/osl/unx/signal.c:288	ign.sa_flags   = SA_RESTART;

My understanding is, that EINTR shouldn't happen again then.

Comment 3 mmeeks 2004-11-30 09:20:42 UTC
Oh; quite possibly :-)

It turns out however - that my report was somewhat inaccurate - I was silently
mounting /proc without thinking since strace was failing - and this is the
repeatable difference.

Without /proc mounted it seems the jre doesn't function sensibly anymore - it's
not clear that this is really an OO.o bug per-se.

Any chance of a:

#ifdef LINUX
if (access ("/proc/meminfo", R_OK))
   fprintf (stderr, "javaldx will not work without /proc mounted\n");

or somesuch ?
Comment 4 kay.ramme 2004-12-09 08:39:33 UTC
Michael, this problem is related to some old SAL stuff accessing the
"/proc/XXXX/cmdline" file for finding out the command line arguments. This has
been fixed with 35209.

Please verify that the problem has indeed vanished, so that I can give this
issue back to you :-).
Comment 5 kay.ramme 2004-12-15 12:18:51 UTC
Michael, please take this back as double 35209. If 35209 is not what you meant,
please send it back.
Comment 6 mmeeks 2004-12-15 14:29:30 UTC
Sure; verifying this is a pain anyhow - I believe (from my strace) it might have
been a jvm bug anyway. So - marking as a duplicate to clear from the radar.
