[Slackbuilds-users] [FIX] Eclipse + xulrunner issue.

[Antonio Hernández Blas]

Hi all.

There's an issue with Eclipse and it's internal web browser that cause
a fatal error with the Java VM. When you launch eclipse you may get a
message like these ones:

This one is from my system (slackware 13.0 + jdk 6u16 + firefox 3.6.3):
#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0xb2ffe82f, pid=6504, tid=3085474000
#
# JRE version: 6.0_16-b01
# Java VM: Java HotSpot(TM) Client VM (14.2-b01 mixed mode, sharing linux-x86 )
# Problematic frame:
# C  [libxpcom_core.so+0x8882f]
#
# An error report file with more information is saved as:
# $HOME/hs_err_pid6504.log
#
# If you would like to submit a bug report, please visit:
#   http://java.sun.com/webapps/bugreport/crash.jsp
# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.

/usr/bin/eclipse: line 3:  6504 Aborted                 /opt/eclipse/eclipse $@

This one is from Howard Pepper's system (slackware 13.1 + jdk 6u20 +
firefox 3.6.3):

Fixes:

You can "simple" install xulrunner:
http://slackbuilds.org/repository/13.0/libraries/xulrunner/
http://slackbuilds.org/repository/13.1/libraries/xulrunner/

But build this package takes quite a lot of time.

The second fix (that doesn't require to install xulrunner but
seamonkey) is to specify to the Java VM the location of xulrunner
(http://www.eclipse.org/swt/faq.php#specifyxulrunner). To make this
edit
/opt/eclipse/eclipse.ini
and add the line:
-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/seamonkey
below the '-vmargs' line.

Note: xulrunner is also inside /usr/lib/firefox, but if you specify
this, you would get a message like:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0xb80ab31d, pid=28349, tid=3086207184
#
# JRE version: 6.0_16-b01
# Java VM: Java HotSpot(TM) Client VM (14.2-b01 mixed mode, sharing linux-x86 )
# Problematic frame:
# C  [libpthread.so.0+0xa31d]  pthread_cond_signal+0xd
#
# An error report file with more information is saved as:
# $HOME/hs_err_pid28349.log
/opt/eclipse/eclipse: symbol lookup error:
/usr/lib/firefox-3.6.3/libxul.so: undefined symbol:
_Z20js_NextActiveContextP9JSRuntimeP9JSContext

This was just tested in an x86 system, i' don't know if this applied
to x86_64 too and BTW, this is not related to /etc/ld.so.conf
misconfiguration or anything like that.

Thanks to Howard Pepper for reminding me about this issue.

Any comment is welcome :)
