Hi I'm using maven to build my project. I haven't seen any errors reported here regarding this particular exception. But some google searching indicates that there seems to be an incompatibility.

I have the following dependency.

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate</artifactId>
<version>3.2.6.ga</version>
</dependency>

Maven detects that Hibernate depends on EHCache1.2.3

I build and run my project and I get: java.lang.ExceptionInInitializerError....
Caused by: java.lang.IllegalAccessError: tried to access method net.sf.ehcache.CacheManager.<init>()V from class org.hibernate.cache.EhCacheProvider

The last version that seems to work is...

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate</artifactId>
<version>3.1.3</version>
</dependency>

Any ideas?

Full stack trace...

So no one has encountered this? Or have I missed something I couldn't find anything in Jira or the forum. Unless I searched wrong.
