Github user mcgilman commented on the issue: https://github.com/apache/nifi/pull/2519 @mattyb149 Previously the loading of Snappy happened during onTrigger. This could lead to the race condition described in the JIRA/PR. Moving this to a static initializer should alleviate the issue. Additionally, the act of service discovery (Java SPI) will load the class. Because of this, I actually don't believe the synchronization here is necessary. Thoughts?
