Steve Loughran commented on HDFS-8705:
--------------------------------------
we can't guarantee that holds across all JDK versions, it crops up
intermittently : https://bugs.openjdk.java.net/browse/JDK-8041791
that's why I'd like to to be used with the case conversions: consistency.
the alternative is to leave as is and convert those demos to tests -but that
won't catch the recurrent problem of the JDK used for release testing not being
the same as people use in production (especially over time).
We now have one place for the operation: let's switch to it. Maybe add in the
javadocs a link to this JIRA and some explanation of reasoning, "we can't trust
JDKs"
> BlockStoragePolicySuite uses equalsIgnoreCase for name lookup, won't work in
