Apache NetBeans version

Apache NetBeans latest daily build

What happened

While opening a NetBeans project (netbeans/java/refactoring.java) netbeans shows an error in in the bottom status line.

This happens only after a fresh netbeans installation is used on a first project scan.

The stacktrace shows

java.lang.NullPointerException: Cannot invoke "javax.lang.model.element.Element.getKind()" because "e" is null
	at org.netbeans.modules.profiler.nbimpl.providers.JavaProfilerSourceImpl$10$1.visitMethod(JavaProfilerSourceImpl.java:639)
	at org.netbeans.modules.profiler.nbimpl.providers.JavaProfilerSourceImpl$10$1.visitMethod(JavaProfilerSourceImpl.java:635)
	at com.sun.tools.javac.tree.JCTree$JCMethodDecl.accept(JCTree.java:993)

The resolution in this case is simple, check the Element e for nulity before dereferencing.

The relevant code is:

          if (e.getKind() == ElementKind.METHOD) {
              ExecutableElement ee = (ExecutableElement)e;
              if (ee.getSimpleName().contentEquals("suite") && // NOI18N
                  (ee.getReturnType().toString().equals(JUNIT_TEST) ||
                   ee.getReturnType().toString().equals(JUNIT_SUITE))) {
                  rslt[0] |= true;
              }
          }

The solution is simple modify first line to

    if (e !=null && e.getKind() == ElementKind.METHOD) {

which has no adverse effect on the logic.
