MemoryAnalyzer Tool based on Eclipse coredumps in libsoup on Fedora 20

I've downloaded MAT ( Memory Analyzer Tool ) for linux x64 and unzipped
on my Fedora 20 installation.

But when starting MemoryAnalyzer, the JVM dumps a core:

[ewer@lxewer mat]$ ./MemoryAnalyzer
#

This problem is already known and there is also a workaround:

Adding
-Dorg.eclipse.swt.browser.DefaultType=mozilla
to the ini-File. In this case the MemoryAnalyzer.ini.

After adding this line, the Analyzer starts.
