A DESCRIPTION OF THE PROBLEM :
The format() method of java.util.Formatter is ending the application abruptly when an exception was expected.

When I am trying to format a character (fromat specifier - c) with invalid values such as negative number (type casted to byte or short) the application is ending abruptly instead of throwing exceptions.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Please execute the sample program.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Since invalid values are passes, exceptions are expected to be thrown. Thus for the "sample program" submitted I expected exception stack trace.
ACTUAL -
Application ended abruptly with message

Exception in thread "main"

REPRODUCIBILITY :
This bug can be reproduced always.
