dependency on javax.xml.bind makes it impossible to jlink on JDK 11

[Sciss]

For example, using pi4j 1.4 in my project, I get

[error] Exception in thread "main" java.lang.module.FindException: Module java.activation not found, required by java.xml.bind
[error]     at java.base/java.lang.module.Resolver.findFail(Resolver.java:877)
[error]     at java.base/java.lang.module.Resolver.resolve(Resolver.java:191)
[error]     at java.base/java.lang.module.Resolver.resolve(Resolver.java:140)
...

This origin of this problem is module-info bug in javax.activation, this issue: fvarrui/JavaPackager#55

See SO comment: Did you consider moving to Pi4J V2? That one is fully modularized and has only slf4j as dependency...

The two reasons for staying on 1.x are compatibility with JDK 8, and complete API change. If I compile my project as such, I am getting >50 errors, as apparently not a single class is the same in 2.x than in 1.x...

Can you try version 1.3 regarding Java 8? 1.4 -> Java 11
