T5: Exception in Autocomplete mixin
Hi
After skipping T4 i decided to give T5 a try.
All 'seems' to come along just fine except for something that has been
baffling me for 2d already now ..
Situation/ environment:
The project is always the same and checked out from svn and runs fine on: a
MacBook Pro with Ubuntu 9.04 within Galileo (Tomcat 6) .. (it is the
quickstart achetype, extended a bit)
The following exception occurs on a:
- MacBook Pro with Snow Leopard & Eclipse 3.5 *and *on a,
- Ubuntu 9.04 on a Mac Pro (the big one) with Eclipse Galileo as well
<Exception>
An unexpected application exception has occurred.
java.lang.ClassFormatError
Invalid length 112 in LocalVariableTable in class file
org/apache/tapestry5/corelib/mixins/Autocomplete
Hide uninteresting stack frames Stack trace
java.lang.ClassLoader.defineClass1(Native Method)
...
</Exception>
As such one would say compare the setups and the diff should be the cause ..
matbe i need glasses but nothing yet.
Question:
What could be the cause of the exception, i.e. where do i start to look to
get this discrepancy ticked off?
Tia,
Fermin DCG

Did you also see the same behaviour across platform and hardware?
Fair enough if it doesn't run properly on 1.6 (not ok but as long as it does
it consistently).
The thing that really puzzles me is the fact that *all* *is* running fine on
Ubuntu on a MacBook but exactly the same situation on a Macpro tanks .. !
Maybe it isn't javassist but java itself and the hardware it runs on?
OSX & java is one flavour, Ubuntu on MacPro != Ubuntu on MacBook
Although i'm not liking the situation i'm *not* convinced it is due to T5
and its approach to bytecode manipulation.
I would be very hard pressed to believe there are only 2 persons working
with J6.
Time permitting i'll try to test it as well on a 64b XP virtualbox.
Spring? Never been there and wil never go .. ;-)
Thx for the feedback for now.

I've tried upgrading javassist to 3.11, it didn't help.
I've run into a lot of trouble because of this javassist problem. It occurs
when compiling with a 1.6 JDK, and it seems to be completely random.
I've managed to overcome this so far by doing binary search debug in my
classes, moving things around until it works. Sometimes you need to change
the order of methods, other times the length and fields.
As I see it, this is a huge problem for T5. I'm having serious problems
explaining to other developers why T5's approach to bytecode manipulation
isn't a risky hack when they see this. It provides good amounts of momentum
to those arguing that "why use an experimental and hacky framework that
almost noone uses when we could be using the nice and stable Spring MVC".
I hate that.

MacBook/Ubuntu:
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)
In Eclipse the same and compliance level 1.6 (except for the tapestry
project that has 1.5)
MacPro/Ubuntu is exactly the same as MacBook/Ubuntu except that i get the
above mentioned error
Same thing for Eclipse on the MacBook on Snow Leopard.
You mean -all- the sources or just the Tapestry sources?
As such this would be ok but retrieving the quickstart via Maven in every
instance should that not give me the same setup everywhere (esp since i have
the prj in svn so all mods are replicated to the other machines as well)
How can i 'override' jassist, the 3.9 version, with the latest 3.11 version?
It seems to be 'rolled into' the T5 set.

This surely looks like a Javassist bug. What Java version are you using?
Meanwhile, try recompiling your sources and reducing the length of event
handler methods.
