I have different opinion there. This exception is quite rare in this function, isn't it? If so, we can optimize common pass by removing explicit checks. It could be performance beneficial.
There other point here, internal exception can be lazy exception or even be optimized out. On DRLVM IMHO if using here arraycopy the exception will be created with lazy stack, which should be much faster then normal exception. If we would had no arraycopy (native function) there, but some other (pure java) function, it could be even possible for JIT to inline and optimize out creation of internal exception. In other words it is not so obvious from performance perspective to have one solution or another. I would personaly prefer implicit check here. -- Ivan 2006/5/12, Mikhail Fursov <[EMAIL PROTECTED]>:
Note that this is not only "beautiful" but also performance oriented way -> do not create extra rethrows if it's possible On 5/12/06, Semukhina, Elena V <[EMAIL PROTECTED]> wrote: > > To have a "beautiful" fix, why don't you just write > > > > System.arraycopy(data, start, value, 0, count); > > > > without trying to catch any exception and rethrow another one? > ArrayIndexOutOfBoundsException, if happened, would be thrown by > System.arraycopy(). > > > > -- Mikhail Fursov
