Bug 62612 NPE in EclipsePreferences.internalGet(...)
I200405171219 + ZRH smoke plugin-export 20040518_1115 After start and shutdown of the Buildmeister runtime I found the following exception. It looks like getTextPreferenceKey() in AbstractAnnotationHover#getHoverInfo() at line 83 returned null. java.lang.NullPointerException at org.eclipse.core.internal.preferences.EclipsePreferences.internalGet(EclipsePreferences.java:479) at org.eclipse.core.internal.preferences.EclipsePreferences.get(EclipsePreferences.java:349) at org.eclipse.core.internal.preferences.PreferenceForwarder.contains(PreferenceForwarder.java:181) at org.eclipse.ui.plugin.AbstractUIPlugin$CompatibilityPreferenceStore.contains(AbstractUIPlugin.java:277) at org.eclipse.ui.texteditor.ChainedPreferenceStore.getVisibleStore(ChainedPreferenceStore.java:525) at org.eclipse.ui.texteditor.ChainedPreferenceStore.getBoolean(ChainedPreferenceStore.java:166) at org.eclipse.jdt.internal.ui.text.java.hover.AbstractAnnotationHover.getHoverInfo(AbstractAnnotationHover.java:83) at org.eclipse.jdt.internal.ui.text.java.hover.BestMatchHover.getHoverInfo(BestMatchHover.java:102) at org.eclipse.jdt.internal.ui.text.java.hover.JavaEditorTextHoverProxy.getHoverInfo(JavaEditorTextHoverProxy.java:69) at org.eclipse.jface.text.TextViewerHoverManager$4.run(TextViewerHoverManager.java:161)
