Our product runs in a third-party Web container on four different platforms 
(Windows, HPUX, RedHat, and Solaris). Our JVM support is determined by the 
third-party vendor's JVM support in the subset of their product line that 
we use, and they have only recently started to support the 1.4 JVM in that 
set. We are therefore stuck until the third-party vendor fully supports the 
upgraded JVM. And the third-party vendor is Sun. :-|
