Bug in Java HashMap Code

I have a bug in the following code.? It works the first time around but not the 2nd.? I think something is not? getting? cleared out.? I can send the entire package to the wining bidder. The finished product will be? to resolve the bug. ? static HashMap<Integer, Integer> reassembledIn = new HashMap<Integer, Integer>(); ? static HashMap<Integer, List<Integer>> reassemblyMap; ? static HashMap<Integer, byte[]> reassemblyFrameData = new HashMap<Integer, byte[]>(); if (reassemblyMap != null && [login to view URL](new Integer(FrameNum)) != null) { ? ? ? ? ? ? List<Integer> framesList = [login to view URL](new Integer(FrameNum)); ? ? ? ? ? ? int total = 0; ? ? ? ? ? ? Iterator<Integer> it = [login to view URL](); ? ? ? ? ? ? while ([login to view URL]()) { ? ? ? ? ? ? ? Integer frame = [login to view URL](); ? ? ? ? ? ? ? byte[] frameData = [login to view URL](frame); ? ? ? ? ? ? ? total += [login to view URL]; ? ? ? ? ? ? } ? ? ? ? ? ? PacketBuf = new byte[total]; ? ? ? ? ? ? it = [login to view URL](); ? ? ? ? ? ? int pos = 0; ? ? ? ? ? ? while ([login to view URL]()) { ? ? ? ? ? ? ? Integer frame = [login to view URL](); ? ? ? ? ? ? ? byte[] frameData = [login to view URL](frame); ? ? ? ? ? ? ? [login to view URL](frameData, 0, PacketBuf, pos, [login to view URL]); ? ? ? ? ? ? ? pos += [login to view URL]; ? ? ? ? ? ? } ? ? ? ? ? ? start_offs = 0; ? ? ? ? ? ? [login to view URL]("Reassembled Frames on Frame " + FrameNum + ": " + framesList).append([login to view URL]); ? ? ? ? ? ? ? ? ? ? ? ? [login to view URL]("Reassembled Frames on Frame " + FrameNum + ": " + framesList); ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? } else if (reassembledInFrame != null) { ? ? ? ? ? ? [login to view URL]("Frame ").append(FrameNum).append(" is reassembled in frame ").append(reassembledInFrame).append([login to view URL]); ? ? ? ? ? ? start_offs = [login to view URL]; ? ? ? ? ? ? break; ? ? ? ? ? } else if ([login to view URL] + startIpOffset == start_offs) { ? ? ? ? ? ? //the buffer has reached the end of the frame, the remaining data is the ethernet trailer ? ? ? ? ? ? start_offs = [login to view URL]; ? ? ? ? ? ? break; ? ? ? ? ? }
