Kaushal,
This is a class loader issue. Javassist isn't finding the
java.lang.Object class. It is configured with a classloader which
should have the system class loader as its parent. So either that
isn't the case or java.lang.Object isn't found by the system class
loader.
Try setting up the thread's context class loader before constructing
the HiveMind registry. Use the class loader which loaded the HiveMind
classes or the java.lang.Object class. E.g.
Thread.currentThread().setContextClassLoader(RegistryBuilder.class.getClassLoader());
HTH,

I am using ikvm to convert jave code to dll file. This java code uses some
thirdparty jar files (eg. log4j.jar, hibernate.jar etc). I use ikvmc to
create .dll file. There is no problem with creating dll.
Then, I am calling some function of that dll from the C# sharp code. I am
using Mono to compile and run C# code. But it gives me following error.
