active Java processes

I have different eBS 12.1.3 environments which are all being used by few people,

but one of them has got more CPU usage, because some Java processes seem to be very active.

This particular environment is NOT used the most, and the server is actually bounced very recently, which would make CPU total time per process be very low

But it isn't

Example

This server is only up for 8 days now, but look at the Java processes:

One has collected 158 minutes of CPU time,

another 229 minutes, and one more has 219

They're all not very constant, being that TOP is switching a lot, but the TOP processes are mainly JAVA processes
