[jira] [Comment Edited] (APEXCORE-767) Duplicate class loading in CLI for single application launch

    [ https://issues.apache.org/jira/browse/APEXCORE-767?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16096937#comment-16096937 ]

This seems to be the root cause for https://issues.apache.org/jira/browse/APEXMALHAR-2511 as well, as I came to the same solution trying to fix it. I will open a PR for this where the proposed solution can be discussed. 
I am still in the process of figuring how the StramAppLauncher works and why the dependencies get loaded multiple times in the first place, is this intended behavior? Otherwise I could also look into what is going on there as well.

> StramAppLauncher will create multiple class loaders in a way that leads to duplicate loading of the same class (while listing app package, then when launching). It also appears that the context class loader is never reset.
