Ebean doesn't start with agent on Tomcat 7

[Rien]

Hi,

I am doing a test with Tomcat 7 and Ebean and when I try to use the
agent I get the error below. It happens at this location:

at
sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.java:
323)
at
sun.instrument.InstrumentationImpl.loadClassAndCallPremain(InstrumentationImpl.java:
338)

Looks like the agent can't be loaded, using tomcat 6 on the same jvm
doesn't give an error.

This is not a big issue for me as I am fine with using tomcat 6 for
now, but anyone got any ideas why this might happen?

Btw, running ubuntu 10.10 64 bit, jvm version is 1.6.0_20, tomcat is
7.0.11

Cheers, Rien

>> but anyone got any ideas why this might happen?

I'd say that either it is not legal to use java.util.Logging in java agents (and tomcat6 didn't enforce this and then is an Ebean bug) or it is a tomcat7 bug.

My guess it is a tomcat7 bug.
