Jeff Storck updated NIFI-5175:
------------------------------
Description:
The following issues have been encountered while attempting to run a Java
1.8-built NiFi on Java 9:
||Issue||Solution||Status||
|Java 9 ServiceLoader requires providers have a default no-arg public
constructor|Add no-arg public constructors|In Progress|
|NiFI boostrap not able to determine PID, restarts nifi after nifi.sh
stop|Detect if NiFi is running on Java 9, and reflectively invoke
Process.pid(), which was newly added to the Process API in Java 9|Done|
----
||Unaddressed issues/warnings with NiFi compiled on Java 1.8 running on Java
9+||Description||Solution||
|WARNING: An illegal reflective access operation has occurred
..._specific class usage snipped_...
Please consider reporting this to the maintainers of
org.xerial.snappy.SnappyLoader
WARNING: Use --illegal-access=warn to enable warnings of further illegal
reflective access operations
WARNING: All illegal access operations will be denied in a future
release|Reflective invocations are common in the code used in NiFi and its
dependencies on Java 1.8|Full compliant migration to Java 9 and using
dependencies that are Java 9 compliant|
