Reported: 2003-02-06 13:39:59 | Status: resolved fixed

I created a project when there were no defined JREs, and got the following NPE: !ENTRY org.eclipse.jdt.ui 4 10001 Feb 06, 2003 12:34:15.392 !MESSAGE Internal Error !STACK 0 java.lang.reflect.InvocationTargetException: java.lang.NullPointerException Stack trace: java/lang/Throwable.<init>()V java/lang/Throwable.<init>(Ljava/lang/String;)V java/lang/NullPointerException.<init>(Ljava/lang/String;)V org/eclipse/jdt/internal/ui/wizards/buildpaths/CPListElement.<init> (Lorg/eclipse/jdt/core/IJavaProject;ILorg/eclipse/core/runtime/IPath;Lorg/eclips e/core/resources/IResource;)V org/eclipse/jdt/internal/ui/wizards/buildpaths/CPListElement.createFromExisting (Lorg/eclipse/jdt/core/IClasspathEntry;Lorg/eclipse/jdt/core/IJavaProject;) Lorg/eclipse/jdt/internal/ui/wizards/buildpaths/CPListElement;
