Re: [Ikvm-developers] Mapping toString, hashCode and equals

[Markus B. <mar...@go...>]

Hi!

Well, I'm not finished, yet, but I have some results I can post:

0. I created a simple HelloWorld.jar and converted it with IKVM.
1. Then I merged the HelloWorld.dll with the IKVM.Runtime and the IKVM.OpenJDK.Core assemblies. 
2. I used the merged assembly in a .NET application
	2.1. I get an error when I use ToString on a object (I will add the bug report right at the end of my mail)

3. I patched the merged assembly using the Reflexil-Tool (I just turned the visibility attribute of the notify, notifyAll and wait-methods in java.lang.Object to "internal").
4. I used the patched assembly in my .NET application 
	4.1. The notify, notifyAll and wait-methods were gone! :)

So far, I think I have to merge more assemblies to get this thing running! In VisualStudio, I did not see the notify, notifyAll and wait-methods! :) That's exactly what I wanted to achieve.

I only merged the Runtime and OpenJDK.Core. And if I add more assemblies, this may do the trick...

Perhaps you can point me some important assemblies that IKVM uses during Runtime?!

Regards,
Markus Bischof

Here comes the Bug-Report (don't forget: This is a failure thrown out of the merged assembly, which has no access to any IKVM assemblies, I think it's really ok that there comes an error!):
