> When specifying an incorrect id generator class in the hibernate mapping file, the following error messages are produced for the exception:
> Caused by: java.lang.RuntimeException: Exception building SessionFactory: could not instantiate id generator
> Caused by: org.hibernate.MappingException: could not instantiate id generator
> Caused by: org.hibernate.MappingException: could not interpret id generator strategy: 
> com.x.persistence.sdfhibernate.SomeIdentityGenerator
> This doesn't show which mapping it's talking about.
> The patch I submitted slightly improves the message by adding the entity name:
> Caused by: org.hibernate.MappingException: could not instantiate id generator for entity com.x.persistence.hibernate.EntityClass
> admitedly I haven't tested it yet, because I am unable to get maven to build hibernate. but i'm working on that now (unable to download org.codehaus.mojo:antlr-maven-plugin:pom:2.0-SNAPSHOT)
