Hi!
I have tried to upgrade our system to more modern tomcat (from 7.0.28) to
7.0.47 and we also get the slow startup due to annotations processing.
In my case it makes tomcat startup go from < 1 second to ~8 seconds and
for development that is annoying, even if it is not critical for
production servers.
This system has ROOT+one webapp. The webapp is not very large, but there
are
350 jars in WEB-INF/lib.
Setting metadata-complete="true" has very little affect (it shaves of
about 0.5
seconds)
As I understand it this has been a known problem since january, anyone know
if there is an open bug on it or a plan to fix it?
Is there any suggestions on what to do more to get a faster startup?
Thread dumps all look like this:
