  It is possible that the usage of throw new myexception; can
  create a exception record that is part of the heap memory.
  The address of this heap memory record is then placed in the
  ezedlr-exception-record control block. If there is a garbage
  collection done, before the exception is processed, the
  address would become invalid and an 0C4 abend could occur.
  
  The way around this is to store the address of the temporary
  record that is used to copy into the heap memory record.
  This temporary record is in the working storage of the
  program that created the throw statement and is not subject
  to garbage collection. The software was been updated to
  reflect this.
  

Problem conclusion

• A fixtest is available for this APAR, however a work around
  is also available. To work around this, simply change the
  EGL statement that does the throw of the user exception
  from:
  
  throw new myexception;
  
  to:
  
  myex myexception;
  throw myex;
