APAR status

• Closed as program error.

Error description

• Liberty (CICS) runs into out-of-memory condition at
  com.ibm.ws.injectionengine.osgi.internal.OSGiReferenceContex
  tImp
  lwhich is comparable to PI66621. yet we deal with another
  cache
  of the injection engine

Problem summary

• ****************************************************************
  * USERS AFFECTED:  Users of IBM WebSphere Application Server   *
  *                  Traditional or Liberty with Dynamic JSP     *
  *                  classes being processed by the              *
  *                  InjectionEngine                             *
  ****************************************************************
  * PROBLEM DESCRIPTION: OutOfMemory Error coming from           *
  *                      InjectionEngine for                     *
  *                      OSGiReferenceContextImpl                *

  * RECOMMENDATION:                                              *
  ****************************************************************
  Users can hit an OutOfMemory (OOM) error when using Dynamic
  JSP
  classes that are regenerated. Memory analysis will point to
  "com.ibm.ws.injectionengine.osgi.internal.OSGiReferenceConte
  xtIm
  pl"  loaded by "com.ibm.ws.injection" occupying a high
  amount of
  memory for ivProcessedInjectionClasses in
  com.ibm.ws.injection.core/src/com/ibm/ws/injectionengine/Ref
  eren
  ceContextImpl.java
  This is caused by the InjectionEngine storing a cache of
  processed classes, since dynamic JSP classes can constantly
  regenerate, they will continue to grow the cache.
  

Problem conclusion

• Injection Engine will be updated to cap the size of the
  Processed classes in the case when we are dynamically
  processing
  injection targets. We do not cap the processed classes cache
  during regular processing done at server startup.
  
  The fix for this APAR is currently targeted for inclusion in
  fix
  pack 19.0.0.3 for Liberty, 9.0.5.0 and 8.5.5.16 for
  WebSphere
  Application Server.  Please refer to the
  Recommended
  Updates page for delivery information:
  http://www.ibm.com/support/docview.wss?
  rs=180&uid=swg27004980
  

Temporary fix

• Only workaround is a server restart to clear out the cache.
