Use as javaagent segfaults java on Ubuntu
Original report by Anonymous.
I tried using ScenicView via the javaagent method. After I load my application, I get a segfault in the java executable (Ubuntu 14.04, java 1.8.0_20, ScenicView built from repository version on 2015-02-13):
A fatal error has been detected by the Java Runtime Environment:

Looking at the hs log, the current thread was the JavaFX application thread. I don't see this crash without ScenicView.
Looks like a nice tool, but I haven't been able to use it yet.

Following up on the above issue (which was me, before I signed up): I see the same behaviour on Mac OS X with 8u20 and 8u31; a segfault that pinpoints sun.invoke.util.ValueConversions::identity (2 bytes) as the crash location, when running with -javaagent
