When I use Eclipse Kepler for Android development, add a new button and right click on a button to change the button's text by clicking on Edit Text...
Then click on New String... I got the following error: Unhandled event loop exception java.lang.StackOverflowError.
Same error doesn't happen with Eclipse Luna or Juno.
When I start the Eclipse Juno for Android SDK, the following dialog with 'Running Android Lint' has encountered a problem. Failed. java.lang.NullPointerException Error message occurred.
Workaround this problem: Window -> Preferences -> Android -> Lint Error Checking. Then uncheck the check box: When saving files, check for errors.
