Error description
A StackOverflowError will occur when a JSF view containing a composite component is accessed when the JVM custom property 'com.ibm.ws.el.reuseEvaluationContext' is set to true. The JVM custom property was added with APAR PM10631. PM10631 enhances memory performance by reusing the same EvaluationContext on a per-thread basis instead of creating a new EvaluationContext object when evaluating expressions. This could cause issues when JSF composite components are used because the EvaluationContext might try to reference itself. A request made to /<context-root>/test.xhtml should result in a StackOverflowError similar to: ?Caused by: java.lang.StackOverflowError at org.apache.el.lang.EvaluationContext.setPropertyResolved(Eva luationContext.java:85) at org.apache.el.lang.EvaluationContext.setPropertyResolved(Eva luationContext.java:85) at org.apache.el.lang.EvaluationContext.setPropertyResolved(Eva luationContext.java:85) ... at org.apache.el.lang.EvaluationContext.setPropertyResolved(Eva luationContext.java:85) at org.apache.el.parser.AstIdentifier.getValue(AstIdentifier.ja va:70) at org.apache.el.parser.AstValue.getTarget(AstValue.java:97) at org.apache.el.parser.AstValue.getType(AstValue.java:85) at org.apache.el.ValueExpressionImpl.getType(ValueExpressionImp l.java:232) at org.apache.webbeans.el.WrappedValueExpression.getType(Wrappe dValueExpression.java:59) at org.apache.myfaces.view.facelets.el.TagValueExpression.getTy pe(TagValueExpression.java:69) at org.apache.myfaces.el.unified.resolver.CompositeComponentELR esolver.getType(CompositeComponentELResolver.java:100) at javax.el.CompositeELResolver.getType(CompositeELResolver.jav a:119) at org.apache.myfaces.el.unified.resolver.FacesCompositeELResol ver.getType(FacesCompositeELResolver.java:122) at org.apache.el.parser.AstValue.getType(AstValue.java:87) at org.apache.el.ValueExpressionImpl.getType(ValueExpressionImp l.java:232) at org.apache.webbeans.el.WrappedValueExpression.getType(Wrappe dValueExpression.java:59) at org.apache.myfaces.view.facelets.el.TagValueExpression.getTy pe(TagValueExpression.java:69) at org.apache.myfaces.view.facelets.el.LocationValueExpression. getType(LocationValueExpression.java:75) at org.apache.myfaces.shared_impl.renderkit._SharedRendererUtil s.findUIOutputConverter(_SharedRendererUtils.java:77)

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty - Expression Language (EL) * * 2.2 * **************************************************************** * PROBLEM DESCRIPTION: A java.lang.StackOverflowError can * * occur when evaluating EL expressions * **************************************************************** * RECOMMENDATION: * **************************************************************** When the JVM custom property 'com.ibm.ws.el.reuseEvaluationContext' is set to true, it is possible for an org.apache.el.lang.EvaluationContext object to reference itself. This can result in a java.lang.StackOverflowError, A stack trace similar to the following should be seen in the logs: Caused by: java.lang.StackOverflowError at org.apache.el.lang.EvaluationContext.setPropertyResolved(Evaluat ionContext.java:85) at org.apache.el.lang.EvaluationContext.setPropertyResolved(Evaluat ionContext.java:85) at org.apache.el.lang.EvaluationContext.setPropertyResolved(Evaluat ionContext.java:85) ... at org.apache.el.lang.EvaluationContext.setPropertyResolved(Evaluat ionContext.java:85) at org.apache.el.parser.AstIdentifier.getValue(AstIdentifier.java:7 0) at org.apache.el.parser.AstValue.getTarget(AstValue.java:97) at org.apache.el.parser.AstValue.getType(AstValue.java:85) at org.apache.el.ValueExpressionImpl.getType(ValueExpressionImpl.ja va:232) at org.apache.webbeans.el.WrappedValueExpression.getType(WrappedVal ueExpression.java:59)
Problem conclusion
EL 2.2 was updated to prevent an EvaluationContext object from referencing itself. The fix for this APAR is currently targeted for inclusion in fix pack 16.0.0.2. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
