Hi David I cannot reproduce your issue (see below).
Since you are not able to catch the exception with a catch-all statement: - Are you sure that the observed NoSuchElementException in the debugger actually stems from code inside of the 'try' block? - What does "crashing" mean? Could it be that the application crashes in some unmanaged code portion executed in some inner 'catch' or 'final' block, before it actually reaches your 'except' block?
