Local fix

Problem summary

• The problem is seen when we have 2 cached entries for a class in
  the Classloader cache and both these have a dependancy for each
  other. Which causes a infinite recursion and finally a crash
  with Stack Overflow.
  

Problem conclusion

• This defect will be fixed in:
  1.3.1 SR11
  1.4.2 SR9
  .
  Dependencies are now managed properly.
  .
  To obtain the fix:
