Hi,

I have been trying to use the -C flag to add external jars with user code and I have observed some strange behaviour.

What I am trying to do is the following:

I have 2 jars, JarWithMain.jar contains the main class and UserJar.jar contains some classes that the main method will eventually execute and also depends on classes from JarWithMain.

Running this works:

flink run .... -C UserJar.jar -c MainMethod JarWithMain.jar args...

Running this leads to no class def found errors in the StreamTask initialization where it reads the functions from the config:

flink run .... -C JarWithMain.jar -c MainMethod UserJar.jar  args...

Did I miss something?

Cheers,

Gyula
