Eclipse errors on startup

Sometimes Eclipse fails to start correctly, refusing to open various views. The following error is typical :-

“Eclipse Galileo Could not open the editor: The editor class could not be instantiated.
This usually indicates a missing no-arg constructor or that the editor’s class name was mistyped in plugin.xml.”

There can be a number of causes, but this suggestion may fix it (worked for me) :-http://www.eclipse.org/forums/index.php?t=msg&goto=443229&S=c7e035ee876b3f197920eb538fdca5c6#msg_443229

The fix is to delete the following file :-
.metadata/.plugins/org.eclipse.jdt.core/variablesAndContainers.dat 

The problem is said to be related to a bug in the data tools plugin. It should be be fixed in version 1.7.2 of the plugin.
