Oracle's top brass might have committed to merging its Java technology with that of Sun Microsystems but the specifics are still being worked out. The plan on how to merge Oracle's JRockit Java Virtual Machine (JVM) and Sun's HotSpot JVM is "still evolving", Oracle principal engineer Mark Reinhold has said. Leads from two JVM …

Please research what you're reporting

Wow, how clueless can you be as a technical journalist? The JVM is NOT an application server. The two are completely different and the app server runs on top of the JVM. The JVMs are HotSpot and JRockit. The appservers are GlassFish and WebLogic.

just dump java servers

I'm so tired of Java servers. Having already 1 in a productive environment requires 2 hours per day in average for maintenance. Just kill it so that we can move to a real application server - by we I mean the whole world.

  seriously?
  
  We have 10 production Java application servers (WebSphere in our case) that require next to no daily maintenance. Now the applications that run in them are a different matter. Some of those require handholding. But that's true of any poorly written application.

It's not necessarily a good idea to merge them

I don't recall, offhand, the performance characteristics of JRockit and HotSpot, but I have a feeling that the former is optimized for server use and the latter for client apps such as browsers. If so, it would make more sense to keep them separate. It's a key rule of engineering that you can't optimize for more than one variable at a time. To put it in everyday terms, if you already have a Ferrari and a pickup truck, you'd be very unwise to try to create a compromise between them.

  Tom,
  
  That sort of analogy does make things a lot easier for the layman to understand.
  
  In the Sun Oracle's case though, it may be that the Best of the Best Engineers and Designers in both Parent Houses follow the path of VW and Porsche with Bugatti being the Passion in a Package and Immaculate Prodigal of a Flowering Love Child.

We were told its dead and we have to buy WebLogic licenses

Sun Java System Application Server (SJSAS), formerly Sun ONE Application Server is dead.

We have grown to hate Oracle and will be moving to WebSphere. Oracle raised prices on WebLogic 47% last year and we just heard they are going to raise all the sparc systems prices another 15% on top of the 15% last year.

Larry is NOT going to get his $1.5B in profit from us.

  Glassfish
  
  Sun One is dead, Glassfish replaces it. It's free as well.

  Have you seen the licensing costs for Websphere!

Those Ferarris have a lot of alloy and composite materials in them...

@Tom Welsh

The Hotspot JVM has both a client and a server version, where the client version does less optimization (or at least: different), than the server variant.
