Trying to add code at the beginning of the method getConnection in the class
weblogic.jdbc.jta.DataSource I got the following error:

I've created a small program that simulates this problem outside the Weblogic
container.
The class can be found inside <Weblogic
home>\modules\com.bea.core.datasource6_1.4.0.0.jar.
And additional dependency which is required in order to load this class (although it is
not needed in order to modify the byte codes) is <Weblogic
home>\modules\com.bea.core.transaction_2.5.0.0.jar.
Both of these files are available when installing Weblogic 10.3.
I suspect this might be some sort of collision with WebLogic's Diagnostic framework.
I'm not sure how calls to WLDF are added, but it is possible they were added by some
other tool for manipulating byte codes (at compile time), in which case this issue is a
bit more interesting (could indicate collisions with certain other AOP tools).
Just for the sake of pin pointing the source of the problem, I also used AspectJ to add
code to the method. It worked fine with no errors.
