I checked on this in the 1.1.1 version of Jacl and I just do not see how
this exception could have been generated.
} finally {
parse.release(); //let go of parser resources <- line 1205
releaseObjv(interp, objv); //let go of objv buffer
}
The only way this line of code would generate a NullPointerException is if
the parse reference was set to null and that does not seem to happen. Well
I guess it could happen if the above call to parseCommand() raised an
exception. Humm, I am going to make a note about this as a possible
problem but if you could provide a small test case that reproduced the
error I would feel a lot better about making a change there. The parser
code is really nasty stuff so changes in there should not be made unless
one is really sure it is "the right thing to do".
