Vladimir Ivanov commented on HARMONY-3628:
------------------------------------------

Seems, it is a bug in the classlib (java.lang.SecurityManager class).

According to specification the classloader may be 'null' in case of 'bootstrap' loader. So the code (currentLoadedClass(), for example) should be updated from:
----
            ClassLoader cl = classes[i].getClassLoaderImpl();
            if (!cl.isSystemClassLoader()) {
----
to something like
----
            ClassLoader cl = classes[i].getClassLoaderImpl();
            if (cl != null && !cl.isSystemClassLoader()) {
----
I'll prepare patch soon.
