RTC Jetty server slow startup

Nicolas Bros (295) | asked Jan 17 '20, 3:27 a.m.
I am developing custom plug-ins on top of RTC.
I followed the Rational Team Concert Extensions Workshop ( to setup the server for development.
The RTC Jetty server takes over two minutes to start each time, which is 3 times more than the previous version I was developing for (6.0.1) which started in about 40 seconds on the same workstation.
Why is that?
Is there a way to speed this up, so that each code modification does not incur a two minute wait?

The JIT seems to be responsible for a big part of CPU usage on start.
Adding the -Xquickstart parameter to the JVM options of the Jetty server launch config improves startup time a lot.
