Gary Dusbabek commented on CASSANDRA-1061:
------------------------------------------
The other approach is to move GCInspector out to its own area so that it gets
compiled separately and ends up in its own jar, then loaded dynamically by the
application if GCInspector is in the cp.
This makes the code look nicer (no reflection), but complicates the set up of
the project.

> com.sun.management.* classes are not available on IBM JDK's a relatively
> quick patch would be to just log a message and let StorageService go on even
> if the GCInspector does not start. With this, at least the released versions
> of cassandra compiled on sun jdk's will work on IBM JDK. Is this enough of a
> work around? (cassandra won't compile on IBM JDK unless GCInspector is
> re-written for both environments using reflection and platform specific
> classes)
