Hi Christian I'll be driving this for Brandon today.
Can you elaborate on why this is not expected to work? We think this should work just fine.
We are using the OSS 6.8.6 RPM downloaded from here:
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-oss-6.8.6.rpm
Previously, we were using the OSS 6.5.4 RPM downloaded from here:
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-oss-6.5.4.rpm
We are not trying to perform any kind of upgrade on Elasticsearch. We are taking our base SW product and installing the OSS 6.8.6 RPM on top of it which worked just fine with OSS 6.5.4
We have never used Xpack or any other security plugin for Elasticsearch.
We see this keystore exception thrown everytime Elasticsearch attempts to start.
The only things I have found online relating to this are:
Which seem to suggest it is an OracleJDK vs OpenJDK problem. As Brandon described we are using OpenJDK and have no way currently of using OracleJDK, but the support matrix states that OpenJDK is supported for this version of Elasticsearch.
