[java] catching Null<T> generates nonsense

[Simn]

class Main {
	static public function main() {
		try {
			throw new Main();
		} catch(e:Null<Main>) {
			trace("caught");
		}
	}

	function new() { }
}

This generates:

	public static void main()
	{
		//line 3 "C:\\GitHub\\HaxeRepro\\source\\Main.hx"
		try 
		{
			//line 4 "C:\\GitHub\\HaxeRepro\\source\\Main.hx"
			try 
			{
				//line 4 "C:\\GitHub\\HaxeRepro\\source\\Main.hx"
				throw haxe.lang.HaxeException.wrap(new haxe.root.Main());
			}
			catch (java.lang.Throwable catchallException)
			{
				//line 3 "C:\\GitHub\\HaxeRepro\\source\\Main.hx"
				haxe.lang.Exceptions.setException(catchallException);
				//line 6 "C:\\GitHub\\HaxeRepro\\source\\Main.hx"
				java.lang.Object realException = ( (( catchallException instanceof haxe.lang.HaxeException )) ? (((haxe.lang.HaxeException) (catchallException) ).obj) : (catchallException) );
				//line 6 "C:\\GitHub\\HaxeRepro\\source\\Main.hx"
				if (( realException instanceof [ !TypeError Null ] )) 
				{
					//line 6 "C:\\GitHub\\HaxeRepro\\source\\Main.hx"
					haxe.root.Main e = ((haxe.root.Main) (realException) );
					//line 6 "C:\\GitHub\\HaxeRepro\\source\\Main.hx"
					haxe.Log.trace.__hx_invoke2_o(0.0, "caught", 0.0, new haxe.lang.DynamicObject(new java.lang.String[]{"className", "fileName", "methodName"}, new java.lang.Object[]{"Main", "source/Main.hx", "main"}, new java.lang.String[]{"lineNumber"}, new double[]{((double) (((double) (6) )) )}));
				}
				else
				{
					//line 6 "C:\\GitHub\\HaxeRepro\\source\\Main.hx"
					throw catchallException;
				}
				
			}
			
			
		}
		catch (java.lang.Throwable typedException)
		{
			//line 2 "C:\\GitHub\\HaxeRepro\\source\\Main.hx"
			throw haxe.lang.HaxeException.wrap(typedException);
		}
		
		
	}

This blocks #7736. Could be a matter of a missing follow or something worse... Advice appreciated!

I'm gonna close some Java-specific issues as unresolved.
