What could possibly go wrong?
In JNLP: <j2se version="1.7"/> User: Java 1.8
What could possibly go wrong?
● Different Java versions installed on client machines● Sometimes javaws wants download and install latest JRE
version● Different behavior depending on Operating System and
installed JRE version● From some point of time apps needs to signed (Self-signed
are blocked)● Application started in sandbox (javaws or jp2launcher)

● We know a target JVM version● Application start outside a sandbox (java instead of
javaws)● We sign only IceBoar jar● Users don’t need admin rights to install JRE

Continuous Delivery
Release artifact to Maven Central is not so easy
● Hard to sign in / create account (need to find link and create an issue)● Manual verification of uploaded artifact
Release artifact to Maven Central is not so easy
Complicated Requirements:● Supply Javadoc and Sources● Sign Files with GPG/PGP● Sufficient Metadata (pom file)● Correct Coordinates (groupId, artifactId, version)● Project Name, Description and URL● License Information● Developer Information● SCM Information
Release artifact to bintray
● Sign in with GitHub● Add new package to maven repository, configure it● Deploy to bintray (from Travis-CI)● You don’t need to sign your artifact
Bintray general repository settings
Bintray deploy to Maven Central
● You can’t store user token password :-( ● This will be manual step :-(
