Local fix

Problem summary

  • The problem is caused by a recursive call to printStackTrace
    which is induced by the redirection of stderr stream and the
    enablement of security debug option
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR11
    6.0.1 SR2
    7.0.0 SR1
    .
    The JVM has been updated to detect the recursive call & stops
    the JVM execution
    

Temporary fix
