About 1916, This is a Widows debugheap overrun issue in the awt code( don't know when this was introduced ). The debug heap marks all allocations with a FD FD FD FD before and after the allocation. During free() it checks to see is that guardarea has been trampled on. If so, it complains with a DAMAGE dialog box that 1916 and some other testsareshowing. The awt code via the array accesors somehow tramples this guard area.
Here is the stack trace from 1916...
harmonyvm.dll!_free_dbg(void * pUserData=0x03bd79b8, int nBlockUse=1)

I looked at 1483 ( it basically changes the int16 to int32 pointers ). We need this. We should commit this and test 1916 with it. If 1916 is still broken, I will debug tomorrow :-) Rana
