Thanks for testing! This sounds good. We need to handle the failing tests separately as they are not immediately related to the up-/downcalls. TestUpcallAsync is failing because of problems with AttachCurrentThreadAsDaemon on AIX. The other ones because libLoaderLookupInvoker.so seems to be broken on AIX.
@JornVernee: You had mentioned a javadoc update. Do we have to wait for anything or can we ship it?
@suchismith1993: Please approve it when you think it's good to go.
