问题
we are currently migrating a Java application from Oracle JDK 8 (application code delivered by JNLP) to OpenJDK 11 (application code delivered as runnable along with a Java Runtime). Although we found more or less a working solution in our test environment we still have following issues:
Our application needs JavaFX and we want to use jlink for building. Is it recommended to use the OpenJFX jmods supplied on https://gluonhq.com/products/javafx to build an appropriate jlink image using OpenJDK, or are there other options?
OpenJFX jmods seems to be officially currently only delivered in version 11 (compiled for JDK 11) on gluonhq, whereas Proguard obfuscation does only work for code compiled for JDK's until version 10 (see https://sourceforge.net/p/proguard/feature-requests/188/). It is unsure when Proguard will support version 11 as well. Should we wait until it does, or what options do we have? Would it be a good option to download and build the OpenJFX sources targeted to version 10 (I have no clue if this is possible out of the box), or even to stay with the Oracle 10 JDK binaries and/or its javafx jmod files as long as Proguard does not understand OpenJDK 11 code?
We are further looking for a tool to create user-friendly runnables for Windows and MacOS (e. g. self-extracting executables without registry modifications). javapackager seems to be not available right now (http://openjdk.java.net/jeps/343 planned for OpenJDK 12) and supports neither cross-compilation nor an auto-update mechanism. So we are looking for a tool which can do both a) auto-updating (loading application code or new jlink images dynamically on startup) and b) building runnables for Windows and MacOS. Is there any good tool supporting something similar to the auto-updating mechanism of Oracle's JNLP launcher that is ready for use in production environments?
For JNLP we apply code signing. Is it still recommended and possible to sign a) our application code located in jlink images and b) dynamically loaded application code, both built with JDK11+?
Thank you for helping, Peter.
