Re: [ULC-developer] Strange class name problem

[ulc rbeeger]

Hi Janak,

Unfortunately, it isn't reproducible. As far as I know it never happened 
twice at the same place. It's totally random.
Sometimes the whole test suite runs without problems, sometimes the problem 
occures once or twice for a whole run of several hundreds of Jemmy tests.
We don't use any custom class loaders besides what's probably included in 
the used libraries. I think CGLib, which is used by Hibernate, does some 
class loading acrobatics, but if that would be the problem, others would 
have experienced it, too.

Cheers,
 Robert

Hi Robert,

Corruption of package names is really strange.

Does it happen for every test or after running certain tests a certain
number of times in Jemmy?

Is it possible for you to narrow down the problem code or send a small
snippet?

Are you using custom class loaders?

Thanks and regards,

Janak

Hi Janak!

So far it only happened during Jemmy tests.
It never happened when running the application directly in the
DevelopmentRunner or with WebStart on a Tomcat.
We are using our own registry providers that extends
DefaultClientCoderRegistryProvider and DefaultServerCoderRegistryProvider.
We also have our own coders. Our registry providers call
super.initializeRegistry().

I don't think it's a problem with the coder registry. Take the following
exception as an alternative example:

Hi Robert,

Can you please give some more details?

When does the error happen? Does it happen when running Jemmy tests or
when
running the application in DevelopmentRunner or some other deployment
mode?

Are you using your own CoderRegistry and coders? If so are you 
inheriting
from AbstractCoderRegistryProvider and calling its
initializeRegistry() to
register default coders like the one for Anything?

Thanks and regards,

Janak

Hi!

For some time now we sporadically get a strange class name
problem. Often
it
results in a NoClassDefFoundError, but sometimes like below it has other
effects. Every time it occures the 23th and 27th character are changed 
in
such a way that newChar = oldChar -1.
Does anyone have an idea where this comes from. We are using JDK
5 Update
8,
ULC 6.1.1, HIbernate 3.2 CR3 and Jemmy 2.2.4.

Any idea is welcome since I don't have any ;)

Cheers,
 Robert
