KB Builder does complete scanning of content of every jar file --------------------------------------------------------------- Key: JBIDE-13837 URL: https://issues.jboss.org/browse/JBIDE-13837 Project: Tools (JBoss Tools) Issue Type: Bug Components: jsp/jsf/xml/html source editing Affects Versions: 4.1.0.Alpha1 Reporter: Viacheslav Kabanovich Assignee: Viacheslav Kabanovich Fix For: 4.1.0.Alpha2 Memory problem were reported https://community.jboss.org/message/804026#804026 At present, KB builder scans for facelet taglibs everywhere in jar files, not only in META-INF folder. That results in complete loading of model objects for jar content, which otherwise would remain unloaded. Once loaded, it is not easy to release them, since objects are shared by projects referencing the same jar. Complete scanning was implemented as fix for https://issues.jboss.org/browse/JBIDE-5764 in February 2010. JSF implementation jsf-impl-2.0.1.jar contains facelet tag libraries in /com/sun/faces/metadata/taglib. However, it is recommended that facelet taglib xml files be packaged into META-INF folder. It seems that jsf-impl-2.0.1.jar is a special case. I suggest that we stop doing complete scanning of all jars and do it only for JSF 2 implementation jar.
