RuntimeException crashes

Collection of 65290 web pages containing stack traces of java.lang.RuntimeException

RuntimeException is an unchecked exception, which means that it is not required to be declared in a method or constructor's throws clause. As a result, it is frequenty used to wrap checked exceptions when implementing methods whose signature does not permit throwing exceptions.

Here are some notable cases:

  • Android developers: If you get this exception from ActivityThread.performLaunchActivity(), it means that there was a problem during instantiating or starting your activity. You should find more help by looking at the root cause of your stack trace.
  • Android developers: If you get this exception from Handler.<init>(), it means that communication between threads is handled incorrectly. Check e.g. if there is something that should happen in the UI thread.
  • Hadoop users: You see this exception when a subprocess fails. This could be caused by a wide variety of errors like missing dependencies, wrong configuration or simply an error in your code. To get more information about it, you have to check the logs of that specific task (you can find it via the job tracker UI).
  • Scala developers: There is a util function in the standard Scala library (Predef.error()) that throws a RuntimeException with a specified message.
