WorkerThread runtime exceptions

[Julien Massiera]

Hi,

 

I have faced a situation where the MCF agent was still up but was not doing
anything after a runtime exception. 

 

My use case was the following :
I have updated the libs used by a repository connector but forgot one.
During doc processing, a runtime exception < java.lang.NoSuchMethodError >
has been throwed because the sub dependency lib was not up to date and thus
the method called was missing. The exception was catched by the WorkerThread
and displayed < Error tossed: .. > but then nothing and the job stayed in
running status and I was not able to abort it until I killed and I restarted
the agent.

 

The catching clause is located in the WorkerThread class at lines 853-857. I
know this is a particular case but I am not sure that the fact the agent
hangs after this exception is a normal behavior and furthermore I can
imagine that it can happen with other unkown runtime exceptions. Is there
something we can do to avoid the agent to be hanging in those cases ? 

 

Regards,

Julien

I'm currently completely consumed with upgrading dependencies for Tika and
CXF.  This is a massive job and won't be done for probably another week or
two.  Once that is done I can try to look into your concern.
