Local fix

• This issue can be worked around by adding Java option
  -Xjit:disableDecimalFormatPeephole
  

Problem summary

• The crash happened when the JIT compiler was accessing an
  invalid field of a C++ object. This was because the JIT compiler
  expected the object to be a different type.
  

Problem conclusion

• The JIT compiler has been updated to take the type of objects
  causing the crash into consideration and prevent the failure.
