question: private static Type [ ] unrollBounds ( final Map < TypeVariable < ? > , Type > typeArguments , final Type [ ] bounds ) { Type [ ] result = bounds ; int i = 0 ; for ( ; i < result . length ; i ++ ) { final Type unrolled = unrollVariables ( typeArguments , result [ i ] ) ; if ( unrolled == null ) { result = ArrayUtils . remove ( result , i -- ) ; } else { result [ i ] = unrolled ; } } return result ; }
target:  Local helper method to unroll variables in a type bounds array.
