Large increase in classes loaded

[ghost]

I have deployed BlackboardVCPortlet in uP 4.0.13 and think it is great! However, since deploying it in production, I have seen a large increase in classes loaded. We used to have 60 - 70K classes loaded in the JVM and that number would remain steady. Since deploying BlackboardVCPortlet, the number of classes loaded goes to 100K+ and keeps rising. One of our servers is up to 180K classes loaded after only 2.5 days of running.

Are you running master (1.0 branch) or 2.0? 2.0 was a pretty heavy overhaul.

I am running 1.2. I don’t think 2.0 was available when I started working on deploying. Unfortunately, I had to do a fair bit of work to change it to work with wsdl v2, which is all we have access to. But have you ever observed that kind of loaded classes growth with any version?

Hi Paul/Tim,

we've been running v1 in production for over a year and I haven't heard of any performance problems, although admittedly we wouldn't necessarily be monitoring the behaviour you've seen.

I'll speak to our support people next week and let you know if we've had to patch anything under 1.x.

Tim, is v2 ready for public consumption?

Cheers,

Richard

Hi Richard/Paul,

UW never went live with version 1.x. We haven't seen any massive class growth with the version we have live. 2.0 should be ready to go. You may have to configure the LDAP config as we didn't utilize it for our implementation. I was going to create a PR for merging 2.0 into master but wanted to see what others thought as well.

Hi Richard and Tim.
Thanks for the info. I'll have a look at 2.0 when It is officially released.
