NPE in 5.2beta2
« on: July 12, 2016, 05:35:49 AM »

Hi, minor issue I'm seeing, I am running an embedded node and each time the node disconnects from the driver I see this NPE.

20:28:44.574 [Thread-0] ERROR org.jppf.server.node.JPPFNode - null
java.lang.NullPointerException: null

Hello,

Thank you for reporting this. Indeed I had already seen it during my tests, and it was fixed in SVN revision 4136.
As far as I remember, this exception is harmless, but it certainly isn't pretty.

If you want to try with the fix (in fact with all the latest fixes), I have automated the publication of a nightly build. The only module that's missing is the .Net port, since my Jenkins machine is a Linux one and I haven't figured yet how to deal with that in a fully automated way.

Sincerely,
-Laurent
