APAR status

• Closed as program error.

Error description

• In Process Designer, while saving a Coach after adding a button
  (or something else) everything's ok in the first 3 Saves.  But
  there is a slight delay in response time between each save,  but
  the save works.
  Then, when we make the 4th save, Process Designer stops
  responding.  There is a "Saving"  message and in the window
  title a "Not Responding" .
  After that a new window "Refreshing Library" also
  with "Not Responding".
  After this, Process Designer stops working and in the
  installation folder some heapdumps and javacore dumps are
  created. The Process Designer interface, becomes grey and stops
  working.
     The cause of this is a memory leak.  Analysis of the
  heapdump shows these objects being leaked

Local fix

• We are able to kill the process and restart.
  

Problem summary

• If user is working in a fairly large process application or
  toolkit, with many coach views, Process Designer will run out of
  memory after a short amount of time after doing a variety of
  actions (such as saving changes to editors, or even
  opening/closing coach view artifacts).
  
  USER AFFECTED:
  Business Process Manager Advanced, Standard and Express users
  leveraging New Generation Coaches and Coach views in a fairly
  large workspace.
  
  PROBLEM DETAILED DESCRIPTION:
  Code change introduced in 8.0.1 included a static resource.  The
  static resource set, while improving temporal performance,
  introduced a memory leak because all loaded layouts were never
  being released from memory.
  

Problem conclusion

• Removed the static resource set, and introduced proper resource
  set usage while still maintaining temporal performance goals.
