      Description

      Null pointer exception messages like this:
      ption in thread "AWT-EventQueue-0" java.lang.NullPointerException
      at jalview.gui.AnnotationLabels.mouseMoved(AnnotationLabels.java:391)
      at java.awt.AWTEventMulticaster.mouseMoved(Unknown Source)

      ..
      Seem to have been introduced with the 2.5 release - when its easy to have the situation where the annotation panel is displayed, but no automated annotations are visible. Even worse, with the console blocking bug, Jalview blocks when lots of these exceptions are raised, making it unusable.

      Need to go through code to check that alignment.getAnnotations() is always verfied non-null prior to being used.
