I am facing the same issue in a different setting: I have a webapplication that calls the local flink execution. Unfortunately the change in the bootloader chain introduces the described problem
Boot classloader App class-loader webapp classloader (knows the flink-classes) it seems that the InstantiationUtil from flink replaces the current context class loader which knows about the flink classes with the blob-classloader with does not have the webappclassloader as parent: Boot classloader App classloader Flink's Blob classloader This is obviously the same problem that also appears when running the local flink election from within an eclipse plugin. Could you help me here? What should I do to tell flink not to ignore the webapp-classloader?
