update for hibernate 6 compatibility

[wglasshusain]

What are your thoughts for Hibernate 6 compatibility?

I did an update that changed to the jakarta.* namespace instead of javax.* namespace and fixed a couple Hibernate 6 compatibility issues. This also requires Java 17. Tests all pass.

The catch is that it will now work with Hibernate 6 and Java 17 but not earlier versions of either.

Thanks @wglasshusain for the PR. I'll try to take care of it and publish to maven these days (not before creating a maintenance branch for hibernate 5.4.x from the current master)
As for the java17 and hibernate6 requirements for the package - I don't think there's another way, so I'm fine with that.
