with J2SE 1.4.2, Itanium IA64 processors are now fully supported. For
Itanium, the 1.4.1 JRE has only a bytecode interpreter. Starting with
1.4.2, we added support for the server JIT compiler.

The performance of applications that make heavy use of Class.forName and
related methods has been significantly improved.

Java Native Interface usage checking via the -Xcheck:jni switch is more
extensive and robust than in 1.4.1.

imiprovements in compile speed and footprint.

bug 4302884 fixed: Now java.applet.AudioClip releases the audio device when
It is no longer used.

besides many minor bugfixes, release 1.4.2 introduces two new look and
feels: Microsoft Windows XP look and feel, and GTK+ look and feel. For more
information, see Swing Changes Since J2SE 1.4.0.
