Description
When attempting to use a Local IBM QMGR with MQ Bindings. IBM States that within the JDK only one instance of the native library can be loaded. I've worked around this issue by symlinking the IBM MQ Libs into nifi/lib/ which is not a good solution. Wondering if this is a known issue with Nifi and the NAR classloader functions or if this is something that can be fixed so that Nifi can correctly work IBM MQ and MQBindings.
This only occurs after you disable and than reenable the controller:

I've worked around this by doing the following:
