JavaBBinder::onTransact - log if env null

This can happen if ProcessState::self()->joinThreadPool() is called
from a thread that is started manually, for instance.

Fatal error is kept (would be SIGSEGV). We don't attach to the JVM
automatically here because it's a resource-intensive operation to
do automatically.
