java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.TypeVariableImpl cannot be cast to com.google.common.reflect.TypeResolver$TypeVariableKey

Hello,

since we switched our application from using playframework 2.2.3 to
playframework 2.3.0 (which might include a lot of dependency changes
like guava), jclouds crashes.
I tried jclouds 1.7.2 and jclouds 1.7.3, both crash. We're using java
1.6.

The crash happens in the following code snippet:
  lazy val context = ContextBuilder.newBuilder("s3")
    .endpoint(server)
    .credentials(user, password)
    .buildView(classOf[BlobStoreContext])

Do you have any ideas how to solve this? The exception is appended:

Glad to hear you've been able to find a temporary workaround at least...

playframework 3.2.0 has guava 16.0.1 included I think.

Using jclouds 1.8.0-SNAPSHOT solved the problem for us, so we're waiting
for the final release now.

Which version of Guava are you using in your application, out of  
interest? 1.7.3 should work with Guava 15.x.

ok, I found this other thread explaining the issue:
http://www.mail-archive.com/user@jclouds.apache.org/msg00779.html

Do you know, when 1.8.0 will be released? It blocks us from migrating to
playframework 2.3.0.

Thank you,
Sebastian
