Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Added methods to c1x_VMExits.cpp Some memos: - the result is not stored in a jobject, but in an oop! => (oop)get_as_jobject() - we get problems with locks hold by the user program when disabling background compilation => currently this makes an assert, we need a better solution
