Hello all,
I found the following NPE in Nifi 1.5.0 version:
2019-11-13 04:19:11,031 ERROR [Timer-Driven Process Thread-5]
o.apache.nifi.jms.processors.ConsumeJMS ConsumeJMS -

Basicaly the TextMessage.getText()
<https://docs.oracle.com/javaee/7/api/javax/jms/TextMessage.html#getText-->
comes in null. According the javadoc is possible.
The fix I did consists on log a WARN and write a empty byte array as
output. In latest version is also not handled the null also. Is it a valid
solution to write in flowfile body an empty array in this scenario?
