APAR status

  • Closed as program error.

Error description

  • Error Message: N/A as this is purely performance issue.
    .
    Stack Trace: N/A
    .
    

Local fix

  • No workaround known.
    

Problem summary

  • We are calling JITHelpers.getHelpers() from known j/l/Class
    method, and getHelpers requires security check which is very
    slow.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.1 SR7
    7.0.0 SR6
    .
    Added a private method JITHelpers.jitHelpers() which does not
    have security checks and call that instead.
    

Temporary fix
