	It is necessary to modify OSGI config.properties to contain org.osgi.framework.bootdelegation=com.sun.btrace, com.sun.btrace.*

	In Glassfish 3.0.1, if I have this in config.properties, I can use btrace to monitor my application classes. But it does not work for JEE classes. For example, if I want to monitor EntityManager, I get java.lang.NoClassDefFoundError: btrace1/ServletMonitor. Any idea?

	Not really The trace class is loaded by the bootclassloader so in theory it should be visible from the whole JVM. This seems like the container classes are loaded by a classloader not delegating to the boot class loader - either by mistake or by design.

	Can you share your Btrace script? Last time I tried to add the package name for the btrace class to solve this problem...
