Not sure now from where that ArrayIndecOutoFBound Exception is coming, I have googled the same but nothing solved out my problem.

Solution

  • Just find below file in your STS install configuration directory and delete it -

    /configuration/.settings/org.eclipse.ui.ide.prefs Blockquote

    beware now you guys would not get previous workspace suggestions like before as we have just deleted the one of the setting file from STS. Hope this will help.
