Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a "Security Configuration Report" is generated via the
  Admin Console, java.lang.OutOfMemoryError errors maybe seen in
  the Deployment Manager Servant region or Base Application Server
  Servant region.
  
  The .phd file will show the following leak suspect, which is a
  large HashMap of held by the
  com/ibm/ws/sm/workspace/impl/WorkSpaceImpl object:

  To confirm this is the problem please reproduce the issue with
  the following trace:
  com.ibm.ws.sm.workspace.impl.WorkSpaceManagerImpl=all=enabled
  
  The following trace point will show how createWorkSpace getting
  called:

  e(WorkSpaceManagerImpl.java:102)
  ............. and so on
  
  By looking at the stack trace from the above trace point we
  observed createWorkSpace being called from the following
  security code:
  ListManagementScopes.java
  ListKeyStores.java
  ListPersonalCertificates.java
  ListSignerCertificates.java
  
  As well as seeing the above createWorkSpace calls, the
  WAS_HOME/profiles/default/wstemp/ directory will contain many
  directories named anonymous* such as below:
  
  anonymous1233674535300
  anonymous1233674535519
