Re: Preventing storm from caching classes

["Bruno D. Rodrigues" <br...@litux.org>]

Any chance your classes are singletons or static classes and the JVM is keeping them around instead of loading the new ones?

I can see this because I have had to keep renaming the classes each time I upload and the only things I see in the jar are my latest classes. Unfortunately, it is old classes that are not in the jar that storm would attempt to run without the renaming. I am running with the 1.7  update 67 jdk.

Is there any chance your build system is not including the newest versions? Can you open the jar file and verify that the correct versions are there?

I am hitting problems where Storm is running old versions of my classes instead of the ones in the currently supplied jar file. I am having to include version numbers in the names of my classes to get the desired code to run.
