oracle owns weblogic, so oracle owns jrockit.

look, as oracle buy sun and will buy your city , and dog  .. soon.. they pick the jrockit GC (wich is know to be better then sun) and put in the new sun jdk 7 .. also jdk benchmarking has double its predecessor in speed..
if you want an state of the art vm, i will stick with sun jvm.. or even the openjdk version 7.. 
i think a lot of good things will get discontinued from this buying but, jvm will improve better now then before... 
just my opinion.. 
unless that a particular VM get tunned better for us "scalers" than sun... but even for that looks that jvm 7 get tunned for other languages as well, and steel winning..

from my experience jrockit and the sun vm have strengths. if they manage
to combine both, the java 7 vm will kick ass as chew bubble gum

Do you have some links to sources for this information? It would be an
interesting read.

Oracle set to merge Java virtual machineshttp://www.infoworld.com/d/developer-world/oracle-set-merge-java-virtual-machines-935?source=footer
"Following the finalization of the acquisition of Sun Microsystems, Oracle announced in its January 27, 2010, Strategy Update webcast that the best features of JRockit would be implemented in the Java 7 JVM" http://en.wikipedia.org/wiki/JRockit

use google, you'll quickly find some sources. but as usual, "twice as
fast" is not a general improvent and applies only to some special cases.
in general, you can probably expect a speed boost around 10-30%
