Local fix

• NA
  

Problem summary

• The problem happens when there is an exception throw when
  initializing the log's handler, and then ErrorManager tries to
  print the error message to System.err, but System.err is
  redirected to a PrintStream owned by WAS which will initialize
  the log again, then it becomes an infinite recursion.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR14
  6.0.1 SR6
  .
  The solution is to add a flag in Logger to mark it is already in
  initialization. When the flag is set, recursive initialization
  of handler is skipped and thus IBM JVM will not get into
  infinite recursion.
  

Temporary fix
