Performance: jweak references not suitable for robust cache architecture
#1 Contrary to the expectations, jweak objects that are destroyed with DeleteWeakGlobalRef() take more GC time than alive one, but with dead objects (see attached test case)
#2 DeleteWeakGlobalRef() does not actually free the memory
#3 jweaks are processed single threaded by the GC
