Nicholas DiPiazza commented on JXPATH-152: ------------------------------------------ Does this issue affect 1.2 release of commons-jxpath library as well? I am calling org.apache.commons.jxpath.CompiledExpression.getValue(JXPathContext) and I too am seeing hundreds of threads stuck trying to get JXPathIntrospector.getBeanInfo. I notice only 1.3 is available from the website. When is 1.4 available to the public? 293 threads with trace:Rate States: {RUNNABLE=293} Stack: - java.util.HashMap.getEntry(HashMap.java:465) - java.util.HashMap.get(HashMap.java:417) - org.apache.commons.jxpath.JXPathIntrospector.getBeanInfo(JXPathIntrospector.java:101) - org.apache.commons.jxpath.ri.model.dynamic.DynamicPointerFactory.createNodePointer(DynamicPointerFactory.java:67) - org.apache.commons.jxpath.ri.model.NodePointer.newChildNodePointer(NodePointer.java:90) - org.apache.commons.jxpath.ri.model.beans.PropertyPointer.getImmediateValuePointer(PropertyPointer.java:127) - org.apache.commons.jxpath.ri.model.NodePointer.getValuePointer(NodePointer.java:238) - org.apache.commons.jxpath.ri.model.beans.PropertyIterator.getNodePointer(PropertyIterator.java:108) - org.apache.commons.jxpath.ri.axes.ChildContext.getCurrentNodePointer(ChildContext.java:56) - org.apache.commons.jxpath.ri.axes.InitialContext.<init>(InitialContext.java:39) - org.apache.commons.jxpath.ri.compiler.LocationPath.compute(LocationPath.java:67) - org.apache.commons.jxpath.ri.compiler.CoreOperationCompare.equal(CoreOperationCompare.java:49) - org.apache.commons.jxpath.ri.compiler.CoreOperationEqual.computeValue(CoreOperationEqual.java:33) - org.apache.commons.jxpath.ri.axes.PredicateContext.nextNode(PredicateContext.java:81) - org.apache.commons.jxpath.ri.EvalContext.nextSet(EvalContext.java:322) - org.apache.commons.jxpath.ri.axes.ChildContext.getSingleNodePointer(ChildContext.java:72) - org.apache.commons.jxpath.ri.compiler.Path.searchForPath(Path.java:183) - org.apache.commons.jxpath.ri.compiler.Path.getSingleNodePointerForSteps(Path.java:159) - org.apache.commons.jxpath.ri.compiler.LocationPath.computeValue(LocationPath.java:82) - org.apache.commons.jxpath.ri.JXPathContextReferenceImpl.getValue(JXPathContextReferenceImpl.java:314) - org.apache.commons.jxpath.ri.JXPathCompiledExpression.getValue(JXPathCompiledExpression.java:57) > Concurrent access on hashmap of JXPathIntrospector > -------------------------------------------------- > > Key: JXPATH-152 > URL: https://issues.apache.org/jira/browse/JXPATH-152 > Project: Commons JXPath > Issue Type: Bug > Affects Versions: 1.3 > Environment: Java5, Windows/AIX > Reporter: pleutre > Assignee: Matt Benson > Priority: Minor > Fix For: 1.4 > > Original Estimate: 24h > Remaining Estimate: 24h > > JXPathIntrospector.registerDynamicClass method can be called in static part > of classes. > If two classes A & B try to registerDynamicClass in the same time a > concurrent access exception can append on hashmap of JXPathIntrospector. > Replace hashmap by concurrent hashmap or synchronized access to these > hashmaps. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
