This could happen in the following copy methods:

• copy(ByteBuffer buffer, int sliceSize, BufferAllocator<ByteBuffer> allocator): if sliceSize is negative, a call to buffer.limit(oldLim + sliceSize) is performed, which causes the BuferOverflowException
  -copy(ByteBuffer destination, ByteBuffer[] sources, int offset, int length): if destination.remaining() is smaller than the number of bytes to copy
