I think this is user error, but the compiler requested I file this report.

The following java code doesn't compiler:

public class test2
{
        static Class m_c = Character.class;

        void xxx(Class c)
        {
                if (c == Character.class)
                {
                }
        }

}

It fails with the following traceback:

wildhorses% javac test2.java
java.lang.NullPointerException

But if you change (c == Character.class) to (c.equals(Character.class))
it compiles.

Or if you change (c == Character.class) to (c == m_c) it compiles.
