Error description
Since the switch from the Commons Expression Language (EL) code to unified EL code in the WebSphere Application Server V7.0 and above used by the JSP Container, the previously available mechanism of controlling EL caching through the com.ibm.wsspi.jsp.disableElCache WebContainer custom property was removed. However, the Commons EL implementation is still shipped with WebSphere Application Server and in some cases still used by customer applications. This APAR restores that EL caching control at the JVM level with a new custom property.
Local fix
modify application code to use the newer unified EL libraries
Problem summary
**************************************************************** * USERS AFFECTED: IBM WebSphere Application Server Version * * 7.0, 8.0 and 8.5 users of Apache Commons * * EL. * **************************************************************** * PROBLEM DESCRIPTION: Applications directly importing * * Apache Commons EL classes will have * * their expressions, values, and any * * converted values cached by the * * expression evaluator with no regard * * to size. * **************************************************************** * RECOMMENDATION: * **************************************************************** Applications that directly use the Commons EL ExpressionEvaluator implementation class will have each unique expression it evaluates cached in a hash map, as well as expressions converted value. This can lead to a lot of memory consumption for applications that have a large number of unique expressions which in some cases can lead to out of memory conditions.
Problem conclusion
The Commons EL code packaged in WebSphere Application Server was modified to allow the caching to be bypassed. To bypass the cache, the following JVM custom property must be set to true: property: com.ibm.disableCommonsElCache values: true / false (default) The fix for this APAR is currently targeted for inclusion in fix packs 7.0.0.29, 8.0.0.6, and 8.5.0.2.
