When I try to create an object array in HackJVM, it crashes with the following exception:

Exception in thread "AWT-EventQueue-0" java.lang.Error: Bug
        at ojvm.operations.BytecodeInterpreter.visit_anewarray(BytecodeInterpreter.java:2174)
        at ojvm.loading.instructions.Ins_anewarray.accept(Ins_anewarray.java:31)

        at org.hacker.worm.WormBot.think(WormBot.java:21)
        at org.hacker.worm.WormModel.moveBot(WormModel.java:84)
...

I've boiled it down to a simple test case. Here's what the code looks like:

Code: Select all

package testbot;
public class Testbot {
    public int think(int dx, int dy, int[][] board, int x, int y, int dir, int[][] enemies) 
    {
        //this crashes
        Object [] tmp2 = new Object[1];

        return dir;
    }
}

Of course, it runs fine when I check "run natively".
Any ideas? Does this use a bytecode that is unimplemented in HackJVM?

sorry, i've fixed this bug in the latest hackjvm for Bitbath, but haven't uploaded it to the wormageddon sdk. i'll try to do that today.

thanks,

Thanks for the quick fix! I'll let you know if the new one still gives me problems...
