EM4J in ESXi

Hi,

I've been reading about Elastic Memory for Java (EM4J). However, I have a question:

- Is EM4J included in ESXi 5.0.x/5.1.x by default?

I understand EM4J comes with vFabric, but I don't know if is included as well by default in ESXi.

I have a lot of VMs using Java app, but they're using Glassfish or JBoss, so I will not use vFabric and I was wondering if is possible to get the benefits of the EM4J without using vFabric.

Is that possible?

Thanks.
