Created: (JASSIST-59) ArrayIndexOutOfBoundsException when replacing field

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

                 Key: JASSIST-59
                 URL: http://j
ira.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().

    Resolution: Rejected

Sorry, I mistaken the bug I'm experiencing with another
possible one commented at tapestry's list. I'll try to
determine the real reason behind the bug, and if it happens
to be javassist related will open a new issue.
