Bug 900447 (JBPAPP6-834)

Workaround: Workaround Exists
Workaround Description: disable and enable the datasource using CLI, after that it will start working in console as well. Another workaround is to force server reload. 
project_key: JBPAPP6

Create a (xa)datasource in admin console. Try to disable it using the appropriate button. This error will happen:

It states that "Data-source service [qrh] is not enabled" even though the datasource has property "enabled" equal "true". 
After you disable the datasource in CLI using :disable operation (this works) and then enable it back -> from this point, disabling and enabling in console will work, just the first time (after creation) it doesn't.

*RESOLUTION* - the datasource has its property "enabled" wrongly set to true, even though it is actually disabled after creation. This is a JCA subsystem issue.
