• When trying to launch the simplest HelloWorld program (which behaves fine with manual javac/java), I get either nothing or:
  Quote:

  
  An internal error occurred during: "Launching HelloWorld".
  org/eclipse/jdt/debug/core/JDIDebugModel

  
  
• I get an "Error log" tab in the console panel, with an error:
  Quote:

  
  Could not create the view: An unexpected exception was thrown.
  

  
  (Follows a consequent NullPointerException stacktrace between sun.util.calendar.ZoneInfoFile.getZoneIDs(ZoneInfoFile.java:785) and org.eclipse.equinox.launcher.Main.main(Main.java:1386))
  
• When trying to access the Installed JREs part of the preferences, I get a popup saying:
  Quote:

  
  Unable to create the selected preference page.
  An error occurred while automatically activating bundle org.eclipse.jdt.debug.ui (162).
  

  
  And the preference tab says "An error has occurred when creating this preference page."
