Bug 325952

Description c.handel 2010-09-22 08:09:25 EDT

Build Identifier: I2010608-911 helios

if a users home directory contains a symlink (like user builder's home is /builder and /builder links to /home/builder) 

The first time eclipse is started and displays a SWT-Browser widget (like the welcome screen) it registers with xul. 

On the second time (or any later) start of eclipse access to a SWT-Browser widget will result in an XPCOM error.

eclipse helios on 64bit linux rhel5.5 with 64bit jdk 1.6.0_21. Tested xulrunner 1.9.2.7 and 1.9.2.9.

Reproducible: Always

Steps to Reproduce:
0) have a user with a symlink in the path to his $HOME

somethink like this

useradd -d /tmp/builder -m
mv /tmp/builder /home
ln -s /home/builder /tmp/builder

1) get the DisplayMozilla code from
http://www.eclipse.org/swt/faq.php#printmozillapath

2) get an eclipse (classic) unpack

3) compile 
javac  -cp .:/eclipse-helios/plugins/org.eclipse.swt.gtk.linux.x86_64_3.6.0.v3650b.jar DisplayMozillaVersion.java

4) run it
java  -cp .:/eclipse-helios/plugins/org.eclipse.swt.gtk.linux.x86_64_3.6.0.v3650b.jar DisplayMozillaVersion

With the jar of eclipse galileo there is no problem.

Removing $HOME/.mozilla/eclipse allows one successful run.
