ZGC Crash

[Mike Rettig]

>>A very interesting observation is that the last internal exception thrown
is the following: /NoSuchMethodError'{0x0000100253de4a20}: static
Lcom/company/nums/biz/compiler/VMethRequest;.<clinit>()V>
(0x0000100253de4a20) thrown [open/src/hotspot/share/prims/jni.cpp, line
1210]

The NoSuchMethodError exceptions are being reported due to serialization.
All the 'clinit' internal exceptions are for objects that are being
serialized. The app isn't attempting to create the objects with JNI.

Any other questions that I can help with?
