#77 Exception at libgcj load

[Olivier Cailloux]

Hello,

I can't use Metrics, using Eclipse SDK 3.1.2 (clean
installation), Metrics plugin 1.3.6 (just installed via
Eclipse software update mechanism), no other plugin.

The installation goes ok, then I restart, select the
Java Browsing perspective, with a Java project opened.
I ask it to show the "Metrics" view. A view called
"Metrics View" indeed appears (until here this is
expected behavior).

BUT the "Metrics View" says :
"Unable to create view: An unexpected exception was
thrown."
Details:

I verified that the file /usr/lib/libgcj.so.6.0.0
indeed exists on my system and is where it is searched.

I don't know how to trace the error...

Thank you for your help.
