Please show us the code at line 190, we cannot guess what it is trying to do.

@CallerSensitive
public static Class forName(String className)
throws ClassNotFoundException {
190 is.. return forName0(className, true,
ClassLoader.getClassLoader(Reflection.getCallerClass()));
}

getClassLoader method is
static ClassLoader getClassLoader(Class caller) {
// This can be null if the VM is requesting it
if (caller == null) {
return null;
}
// Circumvent security check since this is package-private
return caller.getClassLoader0();
}

So one of those classes cannot be found; use your debugger to find out which one it is.
