I try to build Rap runtime from https://github.com/eclipse/rap.

As of Readme all i need t do is just run `mvn clean verify`

however on mac I get

```

Yes, you are right, I can reproduce this behavior with Java 11.

We still use a 1.8 JVM to build RAP as this is our defined target environment. Although it is theoretically possible to use a higher version of the JVM to build than the execution environment later, this makes everything a lot easier.

If you really need to build RAP from the source code, I recommend downgrading your JVM for now.
In the long run, my job is to overhaul the entire build and bring it up to date. Perhaps we have the necessary time for 3.13, but it is already too late for 3.12.

Thanks and regards,
Markus

thanks for prompt reply

export JAVA_HOME=`/usr/libexec/java_home -v1.8`
$ java -version

now show

java version "1.8.0_141"
Java(TM) SE Runtime Environment (build 1.8.0_141-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.141-b15, mixed mode

mvn -version
Apache Maven 3.6.1 (d66c9c0b3152b2e69ee9bac180bb8fcc8e6af555; 2019-04-05T00:30:29+05:30)
Maven home: /usr/local/Cellar/maven/3.6.1/libexec
Java version: 1.8.0_141, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_141.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.14.6", arch: "x86_64", family: "mac"

I'm still getting same issue, did I miss anything ?

There is one more thing...

My successful test was using one of my older Maven installations on disk:

$ mvn -version
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T17:41:47+01:00)
Maven home: /opt/maven/apache-maven-3.3
Java version: 11.0.6, vendor: Ubuntu
Java home: /usr/lib/jvm/java-11-openjdk-amd64
Default locale: en_GB, platform encoding: UTF-8
OS name: "linux", version: "5.3.0-7642-generic", arch: "amd64", family: "unix"

But when I am using the same version as you did I can reproduce your error

$ mvn -version
Apache Maven 3.6.1
Maven home: /usr/share/maven
Java version: 11.0.6, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64
Default locale: en_GB, platform encoding: UTF-8
OS name: "linux", version: "5.3.0-7642-generic", arch: "amd64", family: "unix"

As I said: Something to fix by an overhaul of the build system.
At the moment I don't think it can cause any problems when someone consumes the binary builds.

Regards,
Markus
