Local fix

• NA
  

Problem summary

• Access is denied when trying to read some files. Due to this
  AccessControlException, SyntheticRepository class fails to be
  initialized. Later, when trying to access this class,
  NoClassDefFoundError occurs.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR14
  6.0.1 SR6
  7.0.0 SR5
  .
  The fix resolved the AccessControlException. SyntheticRepository
  class can be initialized properly, hence NoClassDefFoundError
  does not occur.
  

Temporary fix
