[jbossws-issues] [JBoss JIRA] Commented: (JBWS-2683) Inefficient use of JAXBContext leads to excessive classloading

Inefficient use of JAXBContext leads to excessive classloading ---------------------------------------------------------------- Key: JBWS-2683 URL: https://jira.jboss.org/jira/browse/JBWS-2683 Project: JBoss Web Services Issue Type: Quality Risk Security Level: Public(Everyone can see) Components: jbossws-metro, jbossws-native Affects Versions: jbossws-native-3.0.5, jbossws-metro-3.0.5 Environment: JBoss 5.0.1.GA (includes JbossWS 3.0.5) + Java 1.5.0 + MacOSX JBoss 4.2.2.GA + JBossWS 3.0.5 + Java 1.5.0 + MacOSX Reporter: Richard Kettelerij Attachments: gbav-loaded-classes.png, loaded-classes-jboss5.png Despite JBWS-1857 and JBWS-2270 I'm experiencing issues with JAXB in JBossWS 3.0.5. Every time a message passes through my endpoint I see the number of loaded classes rising in JConsole. When -XX:+TraceClassLoading is enabled the JVM shows that the wrapper classes produced by JAXB are (re)loaded with every request/response. This indicates that a new instance of JAXBContext is being used as described in https://jaxb.dev.java.net/issues/show_bug.cgi?id=581 (should have been fixed in JBWS-2270).
