Can not set static ch.sla.jdbcperflogger.agent.DriverInterceptor field about jdbc-performance-logger

[sylvainlaurent]

I think you mixed things with the classpath, the bootstrap classpath and several jars...
Normally you only need to add -javaagent:path/to/jdbc-perf-logger-agent-x.y.z.jar to your JVM arguments and that's it. Nothing to add in the classpath. If that's not the case, please provide the stacktrace of the error.

In the above stack trace, I see this:

Caused by: java.lang.IllegalStateException: cannot assign runtime type class ch.sla.jdbcperflogger.agent.DriverInterceptor (sun.misc.Launcher$AppClassLoader@18b4aac2) to class ch.sla.jdbcperflogger.agent.DriverInterceptor (coldfusion.bootstrap.BootstrapClassLoader@f5ac09b)

which reveals that the class ch.sla.jdbcperflogger.agent.DriverInterceptor has been loaded twice : once by the BootstratpClassLoader, once by the system classloader (sun.misc.Launcher$AppClassLoader), which is not correct. I guess you must have placed some jars in specific directories or you passed specific arguments to the JVM...

The information the jar was loaded twice helped alot. I moved it from a directory that is part of the classpath do a different folder. Now it in fact works without further confgurations.
Thank you!
