org.apache.derby.iapi.services.io.FormatableBitSet.anySetBit()
If any bit is set, return the zero-based bit index of the first bit that is set. If no bit is set, return -1. By using anySetBit() and anySetBit(beyondBit), one can quickly go thru the entire bit array to return all set bit. @return the zero-based index of the first bit that is set, or-1 if no bit is set
