Hi,

I have a project with Hibernate all working with JDK1.4. I have heard we have to use JDK 1.3 now. I use JBuilder, and if I switch JDK from 1.4 to 1.3 in JBuilder, it compiles well, but it won't run.

I get this error message:


java.lang.ExceptionInInitializerError: java.lang.NullPointerException

Whoa! I have not seen this one for a looong time. This was one of the most confusing problems we ever saw. It appears to be a classloader bug in some environments. I was never, ever able to reproduce it.

Are you running on Tomcat by any chance?

Hi,

Well, that's reassuring! No, I am not running Tomcat. It's a Swing application with Hibernate, Springframework and a Cloudscape db. I think there are others in my project (on the other side of the world) who run the same code, mapping files and so on, with JDK1.3.0 and don't have the problem. I'll check that out, but it appears to me there is something on my PC that screws it all up. But what??

Thank you for your help, and best regards from Scotland,
