ClassLoader issue ?

I have 3 plugins.
Each plugin exists in its own jar.
ClientPluginA.jar + ClientPluginB.jar + ServerPluginA.jar.
Common.jar is a jar containing obfuscated classes.
All 4 jars reside in the plugins directory.

All plugins need access to these common classes.

I find that ClientPluginB and ServerPluginA cannot find the (obfuscated) common classes which ClientPluginA is able to find.

I wonder whether ClientPluginA is loaded first, the common classes are also loaded from Common.jar, and these classes become unavailable to the other plugins because they have a separate classloader ?

I am running Servoy Developer.

Any experience or advice appreciated.

see http://forum.servoy.com/viewtopic.php?t=671 how to load/specify libs (you have to provide a .jar.jnlp file which specifies the lib used by the plugin)
