Hello.
As far as I know autoboxing is implemented via valueOf().

i Petr,
In a few places in
src/share/classes/sun/awt/datatransfer/DataTransferer.java you're
eliminating calls to Integer.valueOf() and instead assign the values
directly. Note that this causes the auto-boxing to take place
unconditionally, and thus may hurt the performance a bit. I suggest to
leave the valueOf() calls as they are to take advantage of the
Integer's cache. Please refer to the javadoc for this method for more
details. The same suggestion applies to Long (and maybe Boolean, too?)
