[jbosstools-issues] [JBoss JIRA] (JBIDE-11892) JaxRsMetaModelBuilder runs on non-JAXRS enabled projects

JaxRsMetaModelBuilder runs on non-JAXRS enabled projects -------------------------------------------------------- Key: JBIDE-11892 URL: https://issues.jboss.org/browse/JBIDE-11892 Project: Tools (JBoss Tools) Issue Type: Bug Components: Webservices Affects Versions: 3.3.0.Beta3 Reporter: Fred Bricon Assignee: Xavier Coulon Priority: Critical Fix For: 3.3.0.CR1 Attachments: JaxrsMetamodelBuildJob.png At some point, I had severe performance issues (all cores at 100%) while importing the projects from https://github.com/hibernate/hibernate-search. I disabled all the JBT maven configurators to try to see if this was caused by our maven integration. I can't tell if it's related but, during import, I saw several JAX RS Metamodel build jobs running very slowly, even though none of the hibernate search projects have the jaxrs nature or builder enabled. jstack showed me that : {noformat} "Worker-114" prio=6 tid=0x0000000010134800 nid=0x310 waiting on condition [0x00000000203de000] java.lang.Thread.State: TIMED_WAITING (sleeping) at java.lang.Thread.sleep(Native Method) at org.eclipse.jdt.internal.core.search.processing.JobManager.performConcurrentJob(JobManager.java:259) at org.eclipse.jdt.internal.core.search.BasicSearchEngine.findMatches(BasicSearchEngine.java:214) at org.eclipse.jdt.internal.core.search.BasicSearchEngine.search(BasicSearchEngine.java:515) at org.eclipse.jdt.core.search.SearchEngine.search(SearchEngine.java:584) at org.jboss.tools.ws.jaxrs.core.jdt.JaxrsAnnotationsScanner.searchForAnnotatedTypes(JaxrsAnnotationsScanner.java:172) at org.jboss.tools.ws.jaxrs.core.jdt.JaxrsAnnotationsScanner.findHttpMethodTypes(JaxrsAnnotationsScanner.java:148) at org.jboss.tools.ws.jaxrs.core.internal.metamodel.builder.JavaElementChangedProcessor.processAddition(JavaElementChangedProcessor.java:182) at org.jboss.tools.ws.jaxrs.core.internal.metamodel.builder.JavaElementChangedProcessor.processAffectedElement(JavaElementChangedProcessor.java:122) at org.jboss.tools.ws.jaxrs.core.internal.metamodel.builder.JavaElementChangedProcessor.processAffectedJavaElements(JavaElementChangedProcessor.java:75) at org.jboss.tools.ws.jaxrs.core.internal.metamodel.builder.JaxrsMetamodelBuildJob.run(JaxrsMetamodelBuildJob.java:56) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) {noformat} JaxrsMetamodelBuildJob doesn't seem to filter the projects elligible for JAXRS stuff. I can't say this is the cause of the performance issues I saw (I need to do some profiling) but anyway JaxrsMetamodelBuildJob should never run for non-JAXRS enabled projects.
