---------------------------------
Summary: Suppress illegal access warnings in nifi-bootstrap.log
Key: NIFI-7391
URL: https://issues.apache.org/jira/browse/NIFI-7391
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Affects Versions: 1.11.4
Environment: RHEL 7.7
openjdk version "11.0.6" 2020-01-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.6+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.6+10-LTS, mixed mode, sharing)
Nifi 1.11.4
Reporter: Milco Numan
When starting NiFi, we're running into WARNINGs/ERRORs due to illegal accesses
of certain classes. It's not only the JAXB classes (these can be suppressed),
but if we supress these using
'-Dcom.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize=true', we'll get the
next one
