We finally fixed the issues with Apache Hadoop integration, as upstream

updated their library to not fail on the plain "9" as version number with
StringIndexOutOfBoundsException.

Apache Lucene and Solr 6.6.1 will also be released soon, but it is not yet

decided if we backport everything (the Hadoop upgrade was committed
already, the shell scripts of windows not yet).

Hi Rory,

About the current state:
- Apache Lucene 6.6 and the coming Apache Lucene 7.0 is fully comliant

to

Java 9 and works with "--illegal-access=deny", so the "kill switch" is not
needed.

- Apache Solr 6.6 and Apache Solr 7.0 work (Java wise), but the startup

(shell) scripts don't detect the Java version correctly. I think a fix is in the
make (for Windows and Linux). But if you ignore the startup scripts and

do it

yourself, it works. We applied some fixes for third party libraries that

don't

work correctly (e.g. Hadoop in the version we use).

Older Solr and Lucene versions may still have problems, as the Module

system changed some internal APIs we need for unmapping files, but
generally they should work, but not everything might be with best
performance (e.g. it chooses slow NIOFSDirectory instead on memory
mapping).

We currently do not support Lucene with Automodules, so you *have*

to

use Lucene on classpath. The reason is that the JAR files share same
packages. So you cannot make modules out of Lucene or Solr. We may
support this in later versions, but that's not an important reason for us.

You

can still combine all of Lucene and Solr and make one huge "Uber

Module"

out of it (and that's what I personally recommend), but that's up to the

user.

Hi Uwe & Dawid,

Thank you very much for all your testing of JDK 9 during its
development! Such contributions have significantly helped shape and
improve JDK 9.

Now that we have reached the JDK 9 Final Release Candidate phase [1] ,

I

would like to ask if your project can be considered to be 'ready for JDK
9', or if there are any remaining show stopper issues which you've
encountered when testing with the JDK 9 release candidate.

JDK 9  b181 is available at http://jdk.java.net/9/

If you have a public web page, mailing list post, or even a tweet
announcing you project's readiness for JDK 9, I'd love to add the URL to
the upcoming JDK 9 readiness page on the Quality Outreach wiki.

About the current state:

Older Solr and Lucene versions may still have problems, as the Module system

should work, but not everything might be with best performance (e.g. it chooses

We currently do not support Lucene with Automodules, so you *have* to use Lucene on 
classpath. The reason is that the JAR files share same packages. So you cannot make 
modules out of Lucene or Solr. We may support this in later versions, but that's not an 
important reason for us. You can still combine all of Lucene and Solr and make one huge 
"Uber Module" out of it (and that's what I personally recommend), but that's up

Hi Uwe & Dawid,

Thank you very much for all your testing of JDK 9 during its
development! Such contributions have significantly helped shape and
improve JDK 9.

Now that we have reached the JDK 9 Final Release Candidate phase [1] , I
would like to ask if your project can be considered to be 'ready for JDK
9', or if there are any remaining show stopper issues which you've
encountered when testing with the JDK 9 release candidate.

JDK 9  b181 is available at http://jdk.java.net/9/

If you have a public web page, mailing list post, or even a tweet
announcing you project's readiness for JDK 9, I'd love to add the URL to
the upcoming JDK 9 readiness page on the Quality Outreach wiki.


Looking forward to hearing from you,
Rory

RE: Ready for JDK 9 ?

2017-08-09 Thread Uwe Schindler

Hi Rory,

Thank you for heads-up. I installed JDK 8 update 144 and Java 9 build 181 a 
minute ago. Once the first runs have succeeded, I'll report back.

About the current state:
- Apache Lucene 6.6 and the coming Apache Lucene 7.0 is fully comliant to Java 
9 and works with "--illegal-access=deny", so the "kill switch" is not needed.
- Apache Solr 6.6 and Apache Solr 7.0 work (Java wise), but the startup (shell) 
scripts don't detect the Java version correctly. I think a fix is in the make 
(for Windows and Linux). But if you ignore the startup scripts and do it 
yourself, it works. We applied some fixes for third party libraries that don't 
work correctly (e.g. Hadoop in the version we use).

Older Solr and Lucene versions may still have problems, as the Module system 
changed some internal APIs we need for unmapping files, but generally they 
should work, but not everything might be with best performance (e.g. it chooses 
slow NIOFSDirectory instead on memory mapping).

We currently do not support Lucene with Automodules, so you *have* to use 
Lucene on classpath. The reason is that the JAR files share same packages. So 
you cannot make modules out of Lucene or Solr. We may support this in later 
versions, but that's not an important reason for us. You can still combine all 
of Lucene and Solr and make one huge "Uber Module" out of it (and that's what I 
personally recommend), but that's up to the user.

Hi Uwe & Dawid,

Thank you very much for all your testing of JDK 9 during its
development! Such contributions have significantly helped shape and
improve JDK 9.

Now that we have reached the JDK 9 Final Release Candidate phase [1] , I
would like to ask if your project can be considered to be 'ready for JDK
9', or if there are any remaining show stopper issues which you've
encountered when testing with the JDK 9 release candidate.

Notes. Full JDK 9 downloads are larger than full JDK 8 downloads because they 
include JMOD files so that you can experiment with creating custom run-time 
images.

If you have a public web page, mailing list post, or even a tweet
announcing you project's readiness for JDK 9, I'd love to add the URL to
the upcoming JDK 9 readiness page on the Quality Outreach wiki.

Looking forward to hearing from you,
