Problem summary

  • The problem is caused when a compilation fails because of a
    method being too complicated in terms of number of loops
    resulting in a performance loss.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.1 SR2
    7.0.0 SR1
    .
    The JIT compiler has been updated to reduce the aggressiveness
    of some optimizations that were causing the method to become so
    complicated.
