Exception in thread "Timer-3" java.lang.NullPointerException

Did you find any bugs that should be fixed?

Exception in thread "Timer-3" java.lang.NullPointerException

Postby Diego Cerdán » Sun Aug 04, 2013 1:22 am

Hi guys,

while playing level 18, the Server started behaving weird. I paste the output from the Server bellow. If it happends again I will do a second post so you have more information.

My agent dealed with the situation sending for a LOAD_LEVEL command and could continue playing. ;-)

Cheers,
Diego

Hello Diego
Thank you for pointing out this

It seems that the terminating procedure was interrupted otherwise the server would go to the level selection page when time was up. I never encountered this situation and would like to know more details. E.g. Did you run several agents with the same id ?

I was just running one agent to solve the 21 levels of Poached Eggs. It happend in the middle of level 18.

EDIT: I'm using Server version 1.23.

it seems that you have at least three agent threads registered at the server side. I will wait for your "second post" and at the meanwhile will double check the terminating procedure.

Did you set a time limit? What was your command to start the server?

I did not set any time limit, so default whould be 60 minutes.

I executed the server like this: java -jar Server.jar
