Support Java 9

Came up in #858

[ehennum]

The issue seems to be testing with Java 9 (and, presumably, Java 10 now) and fixing any bugs that show up.

Adding features to exploit the new capabilities of Java 9 and 10 would be in individual RFEs separate from this test item.

Tested develop branch of Java Client API with Open JDK 11 on Linux 3 node MarkLogic cluster running 9.0 nightly server builds (Nov 1 st week builds).

Here are results:

1. Had to upgrade gradlew to use gradle version ```4.10``. Change needed in wrapper properties file.
2. Had to update build.gradle to include JAXB runtime library to 2.3.0
   Used this Gradle dependency in marklogic-client-api project:
   compile group: 'org.glassfish.jaxb', name: 'jaxb-runtime', version: '2.3.0'
3. Minor QA test code changes needed to account for incorrect classloader usage. Need to use application class loader instead of system class loader in ConnectedRESTQA to load test.properties.
4. ml-development-tools project had one test failure. Refer to DescribedBundleTest from tools project fails with OpenJDK 11 due to null classloader #1032.
5. JaCoCo usage had issues and its plugin usage was commented out. Refer to Usage of JaCoCo plugin causes RuntimeException when tests are to be run from gradle/wrapper #1029 , Move usage of JaCoCo to QA / functional tests project in build.gradle file #1030
6. Two tests from ```marklogic-client-api project failed when JDK 11 was used. Refer to UnsupportedOperationException thrown from SSLTest when run on openJDK 11 JVM #1033 and dom.ls.LSException is thrown when QueryOptionsManagerTest is run on open JDK 11 #1034
7. A couple of QA tests were run and loked fine. Will be running entire suite and updating if failures are found.

Assigned to Kiran for time being so that right JDK version to be used can be known, after consulting with Product Mangement, DHF teams.

The JDK versions are being clarified as I write.

Based on Ajit's testing and a few fixes that I checked in, I believe develop can compile and run on 8 - 11.

Have setup Jenkins jobs that handle Java 8, open jdk 9, 10, 11 environments. Had to make gradle (wrapper) changes to handle different Java versions.

9 and 10 are end of life. 8 and 11 have long term support options (till 2024). JDK 12 is now out. The jump from 8 to 9+ was the tricky one. Sure you want to even bother with 9 and 10? 8, 11, and 12 might be better picks. (and 12 will have the same short term shelf life). Come April 16th, the Oracle JDK 8 (and 11, I believe) will require an extended support contract to get those builds. AdoptOpenJDK is the free as in beer LST versions we are going with.

It makes sense that Java shops migrating off 8 are going straight to 11. Whether most Java shops that are already on 9 or 10 are quickly moving to 11 is less clear.

Our direction for testing is to move to OpenJDK with the premise that it gives us the broadest set of environments.

I'm managing the transition at our 350k person shop, and this has been a tremendous amount of ... fun. * Oracle requires a commercial license to run on JDK 8 as of January. JDK 8u201 is likely the last publicly available version. April 16th is when the next set of Oracle release hits - for those with an extended support contract. (For example, 7u80 is the last public build, 7u211 is the current build) * Oracle will have a 'patched' version of 11 for extended support customers. For those doing it for free, they must go to 12. 11 Was identified as an LTS version. * Adopt OpenJDK has a LTS version of 8 and 11. (and also a 12) . They dropped 9 and 10 downloads. * Oracle dropped 9 and 10 downloads * RHEL has 8 and 11 OpenJDK LTS Linux versions. $20 unknown - what does that mean for Centos users. RHEL consumers are covered by the license. 9 and 10 appear to be dropped. * RHEL has 8 and 11 OpenJDK builds for windows, with paid support. * Amazon is supporting a free as in beer version of 8 and 11. (Works nice too) This was a nice write up of the different blog options out there. https://blog.joda.org/2018/09/time-to-look-beyond-oracles-jdk.html?m=1 And download links. If you have JDK 9 and 10 media - hand on to it, because those binaries will be hard to come by in a few months. https://access.redhat.com/articles/1299013 https://adoptopenjdk.net/ https://aws.amazon.com/corretto/

Poking around - the latest release of adoptopenjdk does still show the 9 and 10 versions. You just get the tar.gz version, so if you are setting up Linux # tar -xvf OpenJDK11U-jdk_x64_linux_hotspot_11.0.2_9.tar.gz -C /usr/lib/jvm # vi /etc/environment PATH=$PATH:/usr/java/jdk-11.0.2+9/bin: JAVA_HOME=/usr/java/jdk-11.0.2+9 # update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-11.0.2+9/bin/java 2 # update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk-11.0.2+9/bin/javac 2 # update-alternatives --config java # update-alternatives --config javac For those on a mac, with homebrew (https://brew.sh/) As an elevated user... $ brew tap AdoptOpenJDK/openjdk $ brew cask info adoptopenjdk11 $ brew cask install adoptopenjdk11 You can do 8 with adoptopenjdk8
