Hi,

I have three below bundles:

1) Core-bundle.jar : In this JAR I have a class that is used for dynamic loading of the class(using TCCL: Thread.currentThread().getContextClassLoader()). I have placed this jar in usr repository.

2) Service-bundle.jar - This is using Core-bundle.jar to load its classes and imports Core-bundle.jar. I have placed this jar in usr repository.

3) Application-bundle.par(PAR) - This bundle is importing the Service-bundle.jar and Core-bundle.jar. I am deploying this par in pickup folder.It will create synthetic bundle.

In Virgo 3.5.0 i am getting the below error:

I am using below code for loading the classes in in Core-bundle: com.core.bundle.config.xml.Parser

ClassLoader loader = Thread.currentThread().getContextClassLoader();
loader.loadClass(className);

Same deployment is working fine in Virgo version 3.0.1 but i am getting the above error in 3.5.0

While analysing the logs I found that with 3.0.1 version class delegation start with [bundle=Application-par-1-Application.TestService_1.0.0](here TestService is the jar inside PAR) and load the imported classess successfully but with 3.5.0 delegation starts with synthetic context [bundle=Application-par-1-synthetic.context_1.0.0] and not able to load the classes hence throwing Class not found exception.

Can you please suggest why synthetic context throwing the Class not found exception.
