Building and running that example as it is with no modification does not work as I am getting the following error message: !MESSAGE Possbible annotation mismatch: method "public void hello.parts.SampleView.createPartControl(org.eclipse.swt.widgets.Composite)" annotated with "javax.annotation-api:1.2.0:javax.annotation.PostConstruct" but was looking for "javax.annotation.PostConstruct [via bootstrap classloader]" Looking at the jar files within the eclipse /usr/lib/eclipse/plugins I noticed that there are jar files pointing to glassfish: /usr/lib/eclipse/plugins/javax.annotation-api_1.2.0.jar -> /usr/share/java/glassfish-annotation-api.jar /usr/lib/eclipse/plugins/javax.el-api_3.0.0.jar -> /usr/share/java/glassfish-el-api.jar /usr/lib/eclipse/plugins/javax.inject_1.0.0.v20091030.jar -> /usr/share/java/atinject.jar /usr/lib/eclipse/plugins/javax.servlet-api_3.1.0.jar -> /usr/share/java/glassfish-servlet-api.jar /usr/lib/eclipse/plugins/javax.servlet.jsp_2.3.2.b01.jar -> /usr/share/java/glassfish-jsp-api/javax.servlet.jsp-api.jar specifically the javax.annotation-api_1.2.0.jar is different from the other Eclipse downloaded from https://www.eclipse.org/downloads/packages It comes as javax.annotation_1.2.0.v201602091430.jar which is differen Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.
