(Rhino Graveyard :: Core, defect)

I have large javascripts for which I created some tests. The newest version of
Rhino (1.6R1) reports ArrayIndexOutOfBoundException when running the tests.
Older version (1.5R4.1) does not - but the bug might be there also. I am using
jWebUnit/HttpUnit to perform the tests. 

The exception shows method Interpreter.recordJump, exactly this line:

itsData.itsICode[offsetSite] = (byte)(offset >> 8);

So I have added these lines before it:

int capacity = itsData.itsICode.length;
int capacityNeeded = offsetSite+2;
if( capacity<capacityNeeded) {
    increaseICodeCapasity( capacityNeeded-capacity);
}

And it works correctly.

I am not sure it resolves actual problem, but it works for me. 

Reproducible: Always

This bug is probably a duplicate of 292324 - somehow i missed it earlier.
