I grabbed the latest version of maven so as to run with exactly the same
version of maven. Building current development (reset to 3.7.0-SNAPSHOT)
worked for me.
The javadoc doc for 3.7.0 is already loaded onto jena.staging.
We now have 4 (if you include jenkins) independent reports of success.
It must be quite frustrating but if there is a non-deterministic bug in
the javadoc:attach-javadocs goal, there is not a lot we can do.
The update to plugin-javadoc:3.0.0 was necessary to run with a Java9 JDK
but you could try locally running with an earlier one. (Or skip javadoc
because it is on the web and can be downloaded in javadoc jars.)
There is some recent stackoverflow foo that looks like it but it seems
to be Java10 related.

There is a fix in PR#391.
I've run the test case umpteen times now without incident and done
performance times of bulkloading, which is about as write intensive as it
gets.
The worse slow down I observed (difference of a 3.6 and 3.7-fix) when
loading 25M BSBM triples was 3%. Usually it's 1%. Larger loads will be
dominated by I/O costs so what is a CPU-related fix will be overtaken (I
hope!). It did in the testing I did.
So this email cancels RC1 and I'll start again.

JENA-1516 looks serious and fixable.
I'd like time to verify the fix that I have. As is often the case,
finding the concurrency problem is a lot more time consuming than fixing an
identified problem.
The WIP fix is available at
https://github.com/afs/jena/tree/jena-1516_ObjectFileStorage
if you are really interested.
If that fix looks good, I propose cancelling this RC and doing a new one
to include the fix.
If the fix does not look good, and it has taken quite a heavy sustained
concurrent load to get anything to go wrong (carefully parallel 100
updates, 100 queries, 50 threads and it still does not happen every time),
it seems better to continue RC1 and get a good fix done.
Adam, Chris - thank you for the time to assess RC1. There should be very
little change between RC1 and a possible RC2.
(not sure if SUSPENDED is a recognized state for a VOTE - think of it as
the RM needs time to do some more checking)

Hi,
Here is a vote on a release of Jena 3.7.0.
This is the first proposed candidate for a 3.7.0 release.
There are process changes.
Deadline:
2018-04-01 22:00 UTC
April 1st!
==== Process Changes
1/
MD5 files are being discouraged because MD5 is not secure. Projects are
now asked to not publish md5.
There are no md5 files in the proposed dist/jena area - files on Apache
hardware.
There are sha1 and sha512 checksums.
* The sha512 is in Linux sha512sum checkable format.
* The sha1 is whatever maven generated and is the same as will go to
maven central.
Having the sha1 ties the dist/jena artifacts to maven central (as does
the .asc).
There are md5 and sha1 in the proposes maven repo staging area for
sending to maven central. That part of maven is hardwired to md5/sha1 still.
There's a script to setup the sha512.
2/
To establish the proof chain for signed artifacts in /dist/project/, I
have been asked to try out the new META files.
https://checker.apache.org/doc/README.html#ch-meta
There are two files
/dist/jena/META
/dist/jena/META.asc
META says who signs what, and is itself signed by the PMC chair.
==== Release changes
55 JIRA:
https://s.apache.org/jena-3.7.0-jira
== Significant Changes
** Java9: Building and running on a Java9 platform is supported
JENA-1461 - Allow ARQ custom functions to be written in JavaScript
JENA-1389 - Return `this` rather than `void` from Dataset (API change)
JENA-1495 - Return Model from PrefixMapping methods (API change)
JENA-1458, JENA-1483 - Transaction Promotion
JENA-1453 - Lucene indexes using a graph field are smaller
JENA-1490 - Working with Blank Nodes with Fuseki
== Upgrades to libraries (runtime dependencies):
No dependency changes.
==== Release Vote
Everyone, not just committers, is invited to test and vote.

Checking needed:
+ does everything work on Linux?
+ does everything work on MS Windows?
+ does everything work on OS X?
+ are the GPG signatures fine?
+ are the checksums correct?
+ is there a source archive?
+ can the source archive really be built?
(NB This requires a "mvn install" first time)
+ is there a correct LICENSE and NOTICE file in each artifact
(both source and binary artifacts)?
+ does the NOTICE file contain all necessary attributions?
+ have any licenses of dependencies changed due to upgrades?
if so have LICENSE and NOTICE been upgraded appropriately?
+ does the tag/commit in the SCM contain reproducible sources?
