Problem with 1.6.2.2 version

[Tim Nelson]

Hi,

We recently updated the Scala 2.7 branch of Lift with version 1.6.2.2
and this is now causing an odd error in one of our tests. This same
code runs fine on the 2.8 branch with 1.6.5.

To reproduce the error you'll need to clone the master_2.7 branch of
Lift. You'll also need MongoDB installed and running. The tests are
skipped if you don't have MongoDB running. I'd be willing to test a
patched version of Specs if you need me to.

The code in question is this file [1] on line 336. GitHub shows it as
line 342. The full stack trace is below.

Note that I'll probably be updating the master_2.7 branch soon to
revert back to 1.6.2.1, so make sure you have the proper version set
in resources/lift-parent/pom.xml

Thanks,
Tim

Hi Tim,

I think I already saw that issue happening before.

There's nothing I can do generically against that except stop calling
the Class.getSimpleName method which seems to be broken in some cases
with Scala 2.7.7 and specs.
I'm still using getSimpleName in 2.8.0 but it seems to have been
fixed.

I would propose that either:

- We try to understand why the JsObj class fails to be loaded (because
I think this is what's triggering the NoClassDefFoundError). Maybe
this can be resolved by changing the packaging scheme?

- I change the implementation specs to cook my own getSimpleName
method based on getName

Eric.

Hi Tim,

I uploaded a version of 1.6.2.2 trying to fix the issue you had:

http://nexus-direct.scala-tools.org/content/repositories/snapshots/org/scala-tools/testing/specs/1.6.2.2-SNAPSHOT

Thanks for telling me if it work ok for you now.

I just built the entire Lift project with this version and everything
worked fine.

Thanks.
