Some might use Plesk but may not have gotten the add-on support for Tomcat.
Even there you don't get much response! I like Plesk, but quite disappointed with the fact that the tech support guys don't come to thier forum. The only way seem to be throwing in $299 a year for email support, and I don't see it worthwhile since I have only one server for production.
openxs yes but it talkes alot of configuring. the same goes for cpanel, it can work fine on cpanel, its the same software so... why should it perform any differently. it all depends on how you configure it.
