Call checkcast before invoking NR instrumentation.
This fixes an issue where the Dalvik VM refuses to load a class with our instrumentation in cases where the inbound object is not the expected type as determined by static code analysis.
Don't attempt to instrument constructors in subclasses of classes we normally instrument.
While we support instrumenting constructors by replacing the call to , we don't support doing this in subclasses. For now, we ignore these cases but may return to adding inline instrumentation to constructors in the future.
Java 7u60 (pre-release) refactored the class in which we were storing our invocation dispatcher.
We've future proofed the agent by storing the dispatcher in another core class.
