ArrayIndexOutOfBoundsException when replacing field access in conditional expression
------------------------------------------------------------------------------------

                 Key: JASSIST-59
                 URL: http://jira.jboss.com/jira/browse/JASSIST-59
             Project: Javassist
          Issue Type: Bug
            Reporter: Carlos Pita
         Assigned To: Shigeru Chiba
            Priority: Critical




When there is a field accessed in method in transformed class, and
be used in one side of condition statement such as

            if (_encoder == null)  // this line may cause error
             {
                 _formSupport.store(this, new RestoreState(_value));
             }
             else
            ...

later on, a Javassist FieldAccess for this field replace the method
body by "$_ = $0._$read_parameter_anchor();", (happens on line 1546 in
InternalClassTransformationImpl.class), then I got
ArrayIndexOutOfBoundsException on methods either write16bit() or
sameLocals().
