I'm wondering if something has changed with DataSourceManager.getInstance() between v1.11 and v1.13 and I need to modify my code or this is a bug.
At v1.11, when I call DataSourceManager.getInstance().getDataSources() I get all the dataSources in my map:

After upgrading Developer Edition to 1.13, the same DataSourceManager.getInstance().getDataSources() only gets a subset of the dataSources:

Can anyone shed some light on what is going on here?
Thanks.
