Question

When turning on JRebel for my JSF project, CPU usage gets too high on each requests & drops down when request has been served. I did looked though the profiler but it was not caused due to my project classes itself.

Prettyfaces seems to be the real culprit here.. See this snapshot:

But why this high CPU usage by Prettyfaces happens only when Jrebel is on, what is causing this ? Where is the problem actually ?

Was it helpful?

Solution

The problem is in JRebel 5.5.0 prettyfaces plugin. You can either disable it, or use JRebel nightly build or JRebel 5.5.1+

OTHER TIPS

I also ran into this. This is definitely an issue with JRebel 5.5.0.

I worked around this problem by using JRebel 5.4.2 instead.
