One reason might be the partial failure of the promise of GC.  What I 
mean is this: when introduced to GC the usual message is that it is 
better than manual memory management and with it software will be more 
robust (i.e. not throwing cores, some may even claim that there are no 
memory leaks) by having the JVM decide when to collect which garbage. 
Also, developers will be more productive etc.  This works remarkably 
well in a number of situations.

However, the enterprise world often has more demanding requirements 
(such as dealing with large memory *and* low latency at the same time). 
  Whoever went through the exercise of tuning GC settings (of which 
there are plenty - just execute [1] on your favorite JVM) for such an 
application will be very reluctant to switch to a new Java version (or 
other garbage collector for that matter).  If you have found a set of 
settings with which your application works reliably as expected then you 
are not easily giving it up because the cost to go through the testing, 
measuring etc. with a new JVM can be significant.

Kind regards
