Problem summary
**************************************************************** * USERS AFFECTED: IBM WebSphere Application Server * * Version 7.0 users of the Unified * * Expression Language (EL). * **************************************************************** * PROBLEM DESCRIPTION: An infinite loop can occur when * * applications that use the EL are * * under load. * **************************************************************** * RECOMMENDATION: * **************************************************************** Under certain timing conditions, a WeakHashMap instance in the ConcurrentCache class can be accessed concurrently. This can result in an infinite loop. Below is an example of the call stack during the infinite loop: at java.util.WeakHashMap.get(WeakHashMap.java:355) at org.apache.el.util.ConcurrentCache.get(ConcurrentCache.java:24) at org.apache.el.lang.ExpressionBuilder.createNodeInternal(Expressi onBuilder.java:95) at org.apache.el.lang.ExpressionBuilder.build(ExpressionBuilder.jav a:151) at org.apache.el.lang.ExpressionBuilder.createValueExpression(Expre ssionBuilder.java:195) at org.apache.el.ExpressionFactoryImpl.createValueExpression(Expres sionFactoryImpl.java:68) at com.ibm._jsp._example._jspx_meth_h_inputText_0(_example.java:200 )
Problem conclusion
Code has been changed to correct the concurrent access. The fix for this APAR is currently targeted for inclusion in fix pack 7.0.0.19. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
