JDecisiontable 2.3.3 works with Java 11

Hi,
JDecisiontable 2.3.3 does work with Java 11 (also called " Java 18.9" according to the new release scheme). It just tested this by successfully
- creating and saving a decisiontable
- saving the test specification
- saving a screenshot made from JDecisiontable

Java: OpenJDK, downloaded from http://jdk.java.net/11/

$ java -version
openjdk version "11" 2018-09-25
OpenJDK Runtime Environment 18.9 (build 11+28)
OpenJDK 64-Bit Server VM 18.9 (build 11+28, mixed mode)

Linux: Debian 9, 64 bit:

$ uname -a
Linux <hostname> 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u5 (2018-09-30) x86_64 GNU/Linux</hostname>

Update: It also builds with Java 11, also if JDecisiontableLib is build with Java 11. There are some Warnings from the Jacoco plugin which I will examine. Sorry, that was my mistake. It was compiled with Java 1.8, not 11.
