Well, the offending code seems to be this line in java.lang.Thread:

   private static final RuntimePermission
       SUBCLASS_IMPLEMENTATION_PERMISSION =
           new RuntimePermission("enableContextClassLoaderOverride");

where "new RuntimePermission(...)" results in your observed error if the 
supplied string returns 0 for length().

So I would assume, that after you modified java.lang.String the magic 
trickery within the VM that creates String objects from String literals in

class files is broken with regard to your modified String class.

I'd try to look there for the problem.

Sorry, that I cannot be of more help.
