--- Comment #4 from Francisco A. Lozano <floz...@gmail.com> ---
I've collected several stack-traces during slow startup times and, when the
startup gets "stalled", the stacks look like this:
"localhost-startStop-1" #15 daemon prio=5 os_prio=0 tid=0x0000000001954000
nid=0x52d1 runnable [0x00007fb50c625000]
java.lang.Thread.State: RUNNABLE

It happens from different places:
- netty loading some classes in
io.netty.util.internal.PlatformDependent.getSystemClassLoader
- spring/aspectj startup in
org.aspectj.weaver.tools.PointcutParser.resolvePointcutExpression
and I guess many others
