Using JavaMelody in a Gradle embedded Tomcat container produces a ClassCircularityError

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Check out the minimal Gradle/JavaMelody project at 
https://github.com/chronodm/gtp-96
2. In the project directory, invoke ./gradlew --stacktrace tomcatRun

What is the expected output?

- The app starts normally, without errors

What do you see instead?

- A stacktrace, of which the relevant section is:

Caused by: java.lang.ClassCircularityError: java/util/logging/LogRecord
    at net.bull.javamelody.LoggingHandler.publish(LoggingHandler.java:109)
    at org.apache.juli.logging.DirectJDKLog.log(DirectJDKLog.java:183)

    at org.apache.catalina.startup.Tomcat$start.call(Unknown Source)
    at org.gradle.api.plugins.tomcat.embedded.BaseTomcatServerImpl.start(BaseTomcatServerImpl.groovy:37)

What version of the product are you using? On what application server, JDK,
operating system?

- JavaMelody 1.50.0, although it also occurs with 1.29.0 (I haven't sampled 
anything in between).
- Tomcat (embedded, via gradle-tomcat-plugin)
- JDK 1.6.0_38 (HotSpot 64-bit server VM)
- Linux Mint

I do not think that this is a javamelody issue. You can certainly reproduce the 
same issue with your own ServletContextListener / Filter or Servlet, and using 
java.util.logging.* or SLF4J.

So it's probably a Tomcat or gradle-tomcat-plugin issue. Resolving as invalid 
here.

Just to help, I suggest to note the versions of gradle-tomcat-plugin, tomcat 
and of JDK in the initial issue.
Then I suggest to test recent versions of JDK and of Tomcat, this may change 
some things.

I was not able to reproduce the issue without JavaMelody—I created a 
ServletFilter that logged all requests with java.util.logging and that worked 
fine. So something about the way JavaMelody uses logging, while not unique, is 
triggering this issue.

FWIW, I'm using the latest version of Tomcat 7 (7.0.54), and when I reran it 
with JDK 1.7.0_51 I got exactly the same error.
