Yeah... I developed a bridge (not a native compiler) from Java to Objective-C for the iPhone (called JocStrap: Java/Objective-C bootstrap, for use with the JamVM, which I also ported) back when the device first came out, and I had a ton of people who would contact me because they thought it would make it so they didn't have to learn Objective-C, or that that would be the only reason to want it...

I then had to keep explaining to these developers that "in fact, to use this kind of bridge, you will need to be both an expert at Objective-C and an expert in Java, or you will likely run into some horrible semantic mismatch between how your code at the boundary operates and what the two runtimes each require"; it seems like the same is true of your J2ObjC (especially with regards to memory management).
