detect osgi/equinox classloaders

[GoogleCodeExporter]

I run Eclipse with losejar javaagent. Here is the output after workbench is
started and it seems like it doesn't show the most part of the VM
classloaders there.

[loosejar]: Found 10548 classes loaded in the JVM.
[loosejar]: Found 3 URLClassLoader(s).
[loosejar]: Summary for [sun.misc.Launcher$AppClassLoader] classloader:

    Jar:
C:\eclipse\eclipse-3.4M5\eclipse\plugins\org.eclipse.equinox.launcher_1.0.100.v2
0080205.jar
    Utilization: 41.67% - loaded 5 of 12 classes.

Summary for [sun.misc.Launcher$ExtClassLoader] classloader:

    No third-party jars detected on this classloader's classpath.

Summary for [org.eclipse.equinox.launcher.Main$StartupClassLoader] classloader:

    Jar:
c:\eclipse\eclipse-3.4M5\eclipse\plugins\org.eclipse.osgi_3.4.0.v20080205.jar
    Utilization: 64.94% - loaded 300 of 462 classes.
