This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '25'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Still seeing the problem on F27:

Installing netty3-3.9.3 does not help.

Ooohhhhhh gggoooooddddd.  This was a nightmare to fix.

1) Downgrade HPPC and versionlock it to 0.6.1 from fedora23.
2) Fix hardcoded (and wrong) classpath in /usr/libexec/elasticsearch:

-BASE_JARS="elasticsearch netty3-3.9.3 lucene4-sandbox hppc jackson-core jackson-dataformat-cbor jackson-dataformat-smile jackson-dataformat-yaml snakeyaml guava compress-lzf t-digest commons-cli joda-time antlr3-runtime apache-commons-lang3 lucene4-core lucene4-highlighter lucene4-join lucene4-memory lucene4-queries lucene4-queryparser lucene4-spatial lucene4-suggest joda-convert java-base64"

thx, it worked for me :)

So, more problems.

1) It can't MLOCKALL because JNA isn't a dependency, nor is it listed in the BASE_JARS.
2) It can't log anything to disk because log4j isn't a dependency, nor is it listed in BASE_JARS.

I got this working, as a terrible terrible hack.  The package as-is in Fedora is a disservice to those trying to use it.

Can you please remove the package from Fedora?
