Thanks Vladimir,
I do have difficulties to understand, how (possibly) different threads do get
involved with your application bootstrapping, without having a full picture of
what is going on in your environment.
Anyway, reading your comment, if it is the case, that your entire Isis
bootstrapping is dependent on another thread to complete some initialization
work, you could consider using following fact about javax.servlet.Filter:
The filters are always initialized during webapp's startup in the order as they
are defined in the web.xml. [1]
You can place another custom filter into your web.xml, that has higher priority
than the WicketFilter, such that it can finish any initialization before Isis
gets bootstrapped.
{code:xml}
WicketFilter
org.apache.wicket.protocol.http.WicketFilter
applicationClassName
domainapp.webapp.HelloWorldApplication
WicketFilter
/wicket/*
{code}

Vladimir Nisevic commented on ISIS-1964:
Hi, we are using latest Sun JDK 8 on RedHat Linux with latest Tomcat8. We
restart tomcat after each redeployment. Meanwhile it happens not no often.
Some of our domain services register in their postConstruct method to an
callback of an additional thread which takes care that database is really
available since this domain domain service needs database to read specific app
settings in order to initialize themselve properly. That was an issue in
previous Isis versions so we solved on that way. That means that some of our
domain services spend some time in postConstruct method waiting and then
continue. But we do not touch Isis bootstrapping at all.

Hi Vladimir, can you give us a short description on what kind of java runtime
environment you are encountering this issue?
Do you have multiple instances of Apache Isis running within the same servlet
container or jvm?
Does this happen only on application redeployment or on a servlet container
fresh-start as well?
Cheers, Andi

By looking at the stacktrace, I would say, that during the process of making a
snapshot (copy) of the specification-cache (basically a java.util.HashMap) the
map gets modified. This can only happen if 2 different threads are involved.
To guard against concurrent modification of the specification-cache, we either
need to replace the HashMap with a ConcurrentHashMap or we synchronize reads
and writes to the cache.
But on second thought, I do believe during Isis Application bootstrapping there
is only a single thread involved. So the reason for seeing this exception could
be related to an issue with the particular java runtime environment where
somehow application bootstrapping does interfere with 'left over' instances
that cause this kind of side effects!?
I myself do work a lot with Apache Isis, and never encountered this kind of
error stack trace.
