To JAR Hell And Back - A Live Migration to Java 9


I'm sure you've heard about compatibility issues with upgrading to Java 9 and beyond, but did you try it yourself yet? This live coding session starts with a typical Java 8 application and runs up against and eventually overcomes the common hurdles:

  • build system configuration
  • dependency analysis with jdeps
  • dependencies on internal APIs and Java EE modules
  • split packages

To get the most out of this talk, you should have a good understanding of the module system basics - afterwards you will know how to approach your application's migration to Java 9 and the module system.
