Local fix

• Issue can be worked around using the -Xnoaot option since it
  only happens when using AOT.
  

Problem summary

• The problem is caused when a method that was initially AOT
  compiled gets redefined to an equivalent method, resulting in
  the JIT trying to load it from the Shared Class Cache (SCC)
  instead of performing a recompile.
  

Problem conclusion

• The JVM has been updated to not load a redefined method from the
  SCC.
