----------------------------------------
Hi [~Bl4ck1c3], I've now even was able to compile the recent master (1.x) using
Java 10 ("installed" on Ubuntu 18.04 as Java 11):
{noformat}
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
% $JAVA_HOME/bin/java -version
openjdk version "10.0.1" 2018-04-17
% ant -d -v clean runtime test
Apache Ant(TM) version 1.10.3 compiled on March 29 2018
...
Detected Java version: 10 in: /usr/lib/jvm/java-11-openjdk-amd64
...
BUILD SUCCESSFUL
{noformat}
When running {{ant test}} the protocol-http(client) unit tests fail with an
error in Jetty used to answer the test HTTP requests:

It's a [known problem when upgrading from Java 8 to
9|https://community.oracle.com/thread/4011800]. Don't know yet how to fix it,
probably requires an upgrade of the Jetty server used for testing.
I've changed the issue title: this will be fixed for 1.15, not for 1.14. Thanks!
