Building with Java 11

[Jonathan Gallimore]

Its very much a work in progress, but I have been trying to get our build
to run on Java 11, with the full set of tests. I'm doing this in a branch
which I have been keeping up to date with master as best as I can.

My code is here: https://github.com/apache/tomee/pull/293, and broadly
speaking, adds these modules:

      <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.0</version>
      </dependency>
      <dependency>
        <groupId>org.glassfish.jaxb</groupId>
        <artifactId>jaxb-runtime</artifactId>
        <version>2.4.0-b180830.0438</version>
      </dependency>
      <dependency>
        <groupId>com.sun.xml.ws</groupId>
        <artifactId>jaxws-rt</artifactId>
        <version>2.3.1</version>
        <type>pom</type>
      </dependency>
      <dependency>
        <groupId>com.sun.xml.ws</groupId>
        <artifactId>rt</artifactId>
        <version>2.3.1</version>
      </dependency>
      <dependency>
        <groupId>javax.activation</groupId>
        <artifactId>javax.activation-api</artifactId>
        <version>1.2.0</version>
      </dependency>
      <dependency>
        <groupId>com.sun.activation</groupId>
        <artifactId>javax.activation</artifactId>
        <version>1.2.0</version>
      </dependency>
      <dependency>
        <groupId>org.jacorb</groupId>
        <artifactId>jacorb</artifactId>
        <version>3.9</version>
      </dependency>
      <dependency>
        <groupId>org.jboss.spec.javax.rmi</groupId>
        <artifactId>jboss-rmi-api_1.0_spec</artifactId>
        <version>1.0.6.Final</version>
      </dependency>

There are some regressions to look at, and there are some errors in the
output that need looking at, but one milestone I have reached is getting
almost all the arquillian tests (only 1 failure) in the build to pass.
Here's my current failures:

In terms of the build artifacts, the additional libraries included are:

FastInfoSet-1.2.15
gmbal-api-only-3,1,0-b001
ha-api-3.1.9
istack-commons-runtime-3.0.7
jacorb-3.9
jacorb-omgapi-3.9
javax.activation-1.2.0
javax.activation-api-1.2.0
javax.annotation-api-1.3.2
javax.jws-api-1.1
javax.xml.soap-api-1.4.0
jaxb-runtime-2.4.0-b180830.0438
jaxws-api
jboss-rmi-api_1.0_spec
management-api-3.0.0-b012
mimepull-1.9.10
policy-2.7.5
rt-2.3.1
saaj-impl-1.5.0
stax-ex-1.8
stax2-api-4.1 (as opposed to 3.1.4)
streambuffer-1.5.6
txw2-2.4.0-b180830.0438
woodstox-core-5.1.0 (as opposed to 5.0.3)
xmlschema-core-2.2.4 (as opposed to 2.2.3)

These are obviously being pulled in as transitive dependencies of
dependencies I mention above, and I'm sure some of them can be removed, but
I'll need to work through them to figure out what.

If folks would like to collaborate on this here, it would be most welcome.

Thanks

Jon
