rave-mongodb compile failure

First time user/setup.  I am using maven (3.0.3) and java (1.6.0_20) but
getting a build failure on the rave-mongodb component.

[ERROR]
/my/path/rave/trunk/rave-components/rave-mongodb/src/main/java/org/apache/rave/portal/repository/impl/MongoModelTemplate.java:[79,39]
type parameters of <T>T cannot be determined; no unique maximal instance
exists for type variable T with upper bounds E,java.lang.Object

I just started following the Getting Started directions here:
http://rave.apache.org/source.html

1. svn co
2. mvn install

Any insights?  I don't really intend to use mongodb for persistence anyway
but didn't want to remove the dependency from the pom if this is something
silly I'm tripping myself over.

It looks like this code was changed a bit in the last few months, not sure
if these are relevant yet...

Thanks.

Thanks Chris -- using java 1.7 I was able to get a successful build.

Welcome to Rave and sorry you ran into a problem on your first attempt.

I believe this may be caused by a bug in your version of the JDK [1].
You'll notice the affected version is 6u20. This particular issue shows it
was fixed in Java 7 but if you look at the related backport links lower in
the bug report it looks like it was back ported to 6u22 and above. Is there
any chance you can try to upgrade your JDK version and try again?

I can confirm it compiles on 6u37.

Also, if you are just looking to run the system you can download the demo
binaries which are all setup to run from here [2].

Thanks,
Chris
