No issues, and here is another one, while Java might have a C++ like syntax to make it more appealing to mainstream, its main influence was Objective-C, not C++.

Hence interfaces, dynamic loading, reflection and so forth.

Interesting.

Bringing it back to a previous point I made, I met someone who claimed to have helped port over the WebObjects framework from Objective-C to Java, and he claimed that while it's not a 1-to-1, you can fairly easily map a lot of the Objective-C semantics to Java, making the porting process not that hard.

Yes, they are quite close.
