Sun Microsystems Inc was last week making noises that it wanted to make some acquisitions and rumor says it may be interested in Borland International Inc, since Borland has a Java-based JIT compiler which Netscape Communications Corp has licensed. Netscape Communications Corp Navigator users will soon be able to run Java applets up to 10 times faster now that Netscape has licensed Borland’s AppAccelerator just-in-time dynamic compiler. AppAccelerator reads the intermediate byte code produced by Java development tools and translates it on-the-fly into machine- executable instructions on the local client system. Initially, AppAccelerator will be available for Windows95 and Windows NT clients.
