Re: [infinispan-dev] Avoid Collections.emptySet() / emptyMap() / emptyList
Hi Erik,
interesting, I'm sure several people will still use Java6 for a while
but wasn't expecting you did, as you can both carefully test your
environment and are aiming to top performance. There are several more
performance goodies in Java7... could you share why you're on 6 ?

An old version which is probably in use in most production environments :)
If they aren't ready to upgrade to JDK7, I doubt they're willing to upgrade
to Infinispan 5.2 :)
FYI, I’m using ISPN 5.2 on JDK6 (on a hacked up JBossESB container). Plus
who knows what wacky configurations you’re supporting on the JDG side.
