Since a few months, I encountered an annoying error in Aptana Studio and Eclipse 3.7 (the autonomous packages, not the packages from the repositories) whenever I tried to do a git or hg action.

I could live without until now, but today, it was really bothering me.

The error is:

{{< highlight text >}} Unhandled event loop exception No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)] {{< /highlight >}}

The log file showed the following backtrace:

{{< highlight text >}} !ENTRY org.eclipse.ui 4 0 2011-12-16 17:17:30.825 !MESSAGE Unhandled event loop exception !STACK 0 org.eclipse.swt.SWTError: No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)] at org.eclipse.swt.SWT.error(SWT.java:4109) at org.eclipse.swt.browser.Mozilla.initMozilla(Mozilla.java:1739) at org.eclipse.swt.browser.Mozilla.create(Mozilla.java:656) at org.eclipse.swt.browser.Browser.(Browser.java:119) at com.aptana.git.ui.internal.actions.CommitDialog.createDiffArea(CommitDialog.java:237) at com.aptana.git.ui.internal.actions.CommitDialog.createDialogArea(CommitDialog.java:158)

To make it short, after having read a lot of posts about [this](<http://stackoverflow.com/questions/1017945/problem-with-aptana-studio-xulrunner-8-1) problem, it seemed it was enough to give the path to Xulrunner to Aptana.

On my Arch Linux, it was

{{< highlight bash >}} export MOZILLA_FIVE_HOME=/usr/lib/xulrunner-8.0 {{< /highlight >}}

Trying to start Aptana Studio, I had a new error. It simply stated

{{< highlight text >}} XPCOM error -2147467261 {{< /highlight >}}

The solution is that Aptana Studio cannot work with the version of Xulrunner in Arch LinuX repositories because it is too recent.

To solve this problem, I had to install xulrunner 1.9.2 from AUR:

{{< highlight bash >}} yaourt -S xulrunner192 {{< /highlight >}}

The PKGBUILD was broken this morning and ended in a 404 Error when fetching sources. If you have the same problem, here is an updated PKGBUILD <https://gist.github.com/1486851>__

Finally, I put

{{< highlight bash >}} -Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner-1.9.2 {{< /highlight >}}

at the end of the AptanaStudio3.ini file in the Aptana Studio folder. For the package in the Arch Linux repositories, this file is /usr/share/aptana/AptanaStudio3.ini.
