That's of course a problem, but is manageable. But customers are also
extremely happy if they get some new features or better performance
for free (e.g. the new JSR292 implementation in hsx24 which will be in
jdk7u40). And not all JVM features have to be covered by the JCP, most
of them are just implementation details.

But the problem is (and believe me, this statement is backed up by
experience) that costumers are very reluctant to update to new JDK
versions. For many customers even the current release cycles are too
fast. They rather update their hardware than updating their software
stack.
