Local fix

  • Disable PRE optimization in JIT.-Xjit:disablePRE

Problem summary

  • This is a JIT optimization issue. Caused by PRE optimization.

Problem conclusion

  • JIT PRE skip optimizing node for shadow reference requires
spinecheck for NPE.JIT PRE more conservatively fix kill set for
AIOB issue.
