--- Comment #12 from Krishnan Ganapathy <[email protected]> --- We are still able to reproduce this issue in our app deployed on JBoss server (5.1.0). We are using ANT 1.8.2 version which from what i understand contains this fix. Interestingly as mentioned in one of the comments, we are getting this error only on 32 bit m/c with Xmx setting as 1024M. We then lowered it to 800M and this error did not occur. >From our analysis, its seems that whatever be the block size (16M in the patch applied), there is always a chance that this error might occur as there might be stray cases where the native map0 call in the FileChannel class might fail. Hence, the code should fallback on using the read/write methods on FileChannel or use the classic IO to accomplish this copy instead of throwing an IOException. We would like to go ahead, make changes and submit the patch but wanted to know if there are any other suggestions that we can try out. - Krishnan -- You are receiving this mail because: You are the assignee for the bug.
