Improper handling of Java Class object when in native Object mode

[Udo]

When running in native Object mode (as described here) the Java "Class" object becomes a "native" object. 

This leads to problems e.g. when the Java Class object is used as a key in a HashMap, because the method hashCode() is not defined.

E.g. running this code in native Object mode:

    HashMap classNames = new HashMap();

    String fooCmt = "The Foo Class";

    classNames.put(Foo.class, fooCmt);

will throw an exception:

    TypeError: 'undefined' is not a function (evaluating 'key.hashCode()')

As Java "Class" objects are "Java Objects" I would have expected also the "Class" class inherits from the JavaObject class/prototype. But this is not the case when in "native Object" mode.

You can see the issue live at: http://www.abego.org/j2s/J2STest/index.html

Source code for the test case: https://github.com/abego/Java2Script-contrib/tree/master/J2STest/src/main/java/org/abego/j2stest/nativeobjectmode

In fact, lots of methods in Java class object are missed in Java2Script environment. It is considered a defect of J2S and won't be fixed totally for performance reason.

In case you report this problem, I think there are cases using *.class#hashCode. so I just added this method for both normal and j2s.objective.native modes.

See the differences at https://java2script.googlecode.com/svn/trunk/sources/net.sf.j2s.java.core/src/java/lang/Class.js revision 1183 v.s. 1189

For compiled and packed version of this bug-fix, you can download and unzip

http://dev.zhourenjian.com/j2s/j2slib.v20120525.zip

into plugins/net.sf.j2s.lib_2.0.0/j2slib/ , overwrite existed *.js files.

Thanks for reporting bugs.
