Don't sweat the price. You'll pay in other ways

Free whitepaper – The Register Guide to Enterprise Virtualization
QCon Oracle will deliver two Java Virtual Machines (JVMs) based on the
OpenJDK project - one free and the other paid.
That's according to Tweets pouring thick and fast from an Oracle session at
QCon San Francisco, where the database giant mostly repeated its earlier
plans for Java.
Adam Messinger, Oracle vice president of development, told QCon that Oracle
plans to offer a "premium" edition of the JDK in addition to the open-source
JDK.
Both, it seems, will be based on a converged JRockit VM and the Hotspot JVM
from Sun Microsystems. The converged JVM will be released under the OpenJDK
project.
JRockit has world-beating performance, thanks to its garbage collection
features. It also provides hot swapability. You can make changes without
taking a server offline. HotSpot has been considered a generally good all-
round JVM that's reliable, and it has supported more operating systems and
hardware.
Oracle's plan has always been to merge JRockit and Hotspot, and Messinger
was simply repeating the message delivered by Oracle during a strategy
announcement in January.
But Oracle has not said before that it would deliver free and premium
editions of its VM.
Messinger didn't explain how the premium JVM would differ to the free
version, but the premium edition will likely see performance tuning and tie-
ins to Oracle's middleware.
Messinger promised: "There will always be a high-performance gratis JVM."
He didn't say how Oracle would price the JVM, or explain how it would be
offered, according to QCon Tweets.
Should people be worried about the pricing news, especially in view of
Oracle's history of jacking up prices? Oracle recently doubled support costs
for MySQL, which is also open source.
Not according to Messinger, who Tweeters claimed said: "I don't tank [sic]
folks need to be too hung up on this, since we make so much money on Java
elsewhere." That would be the Java Oracle's VM customers use elsewhere, yeah?
Meanwhile, Oracle has officially responded to its double set-back during the
Java Community Process (JCP) executive committee elections.
Henrik Ståh, responsible for product strategy in the Java Platform
Group and an official spokesperson for Oracle on Java SE, has that said
Oracle still "respects" the Apache Software Foundation (ASF) - despite
screwing it by refusing to grant ASF a Java license for its Java SE
implementation Project Harmony.
Ståh congratulated ASF's romp home to re-election on the JCP. Somebody
from Oracle had to, otherwise it would have looked bad.
"Our disagreement around TCK licensing does in no way lower our respect for
and desire to continue to work with Apache," according to Ståh.
We're sure ASF also harbors no bad feelings and wants to put this behind
them too. Oh, wait...
Oracle's JCP man proceeded to chastise those who voted against Hologic
during the election, blocking it from getting a seat on the EC group driving
Java SE and EE.
Developers saw Hologic as an Oracle supporter being brought onboard to pack
out the JCP. The Reg understands developers either voted against Hologic or
abstained after members actively encouraged their colleagues to block
Hologic's nomination. Ståh maintained Oracle was attempting to bring
more of a customer focus to the JCP by nominating Oracle - it just so
happened the customer in question was one of Oracle's, referenced in glowing
terms on the giant's website.
"We believe that the lobbying against him was misguided and rather
unfortunate for the community." Ståh said. You can read the rest of St&
#229;h's statement here. ® |
