Hi JPDA folks,

I think we've found a bug in the ReferenceTypeImpl.isPrepared method. I
checked the bug database and I didn't find anything that looked related.

The current ReferenceTypeImpl.isPrepared method is ...
> public boolean isPrepared() {
> // This ref type may have been prepared before we were getting
> // events, so get it once. After that,
> // this status flag is updated through the ClassPrepareEvent,
> // there is no need for the expense of a JDWP query.
> if (status == -1) {
> getModifiers();
> }
> return isPrepared;
> }
>

The problem is that getModifiers does not update the status or
isPrepared fields. I think the call to getModifiers should be replaced
with a call to updateStatus. Calling updateStatus will call decodeStatus
which will set the isPrepared field. I think isPrepared should be more
similar to isVerified and isInitialized.

Maybe it should be like this...
    public boolean isPrepared() {
        // Once true, it never resets, so we don't need to update
        if ((status & JDWP.ClassStatus.PREPARED) == 0) {
            updateStatus();
        }
        return (status & JDWP.ClassStatus.PREPARED) != 0;
    }


What do you think?
