Document differences between Java and JVM targets.

I read that the JVM target, "gets rid of issues with incompatibility between Haxe and Java type parameters."

It would be best if any compatibility issues with Java and differences between the two targets were detailed in section 12.8.

I wouldn't really know what to document in that regard. The Java target generates .java files, the JVM target skips that step and makes a .jar. Not sure what other kind of information end users really need to learn about.

Me neither! Maybe @waneck can pipe in?

Simn says that JVM target relies on some API which is unavailable on some android devices ten months ago. Simn, can you give more details about this?

That was when it was using MethodHandle, which is no longer the case. @ibilon tested it on various android versions and concluded that it seems to work fine.

I left a comment on the original blog post about the type incompatibility, but it would still be good to include any differences between the targets. Even if it is just that the JVM target doesn't require OpenJDK to compile everything.
