Java 11 introduces far-reaching changes in the bytecode specifications:
* JEP 181: Nest-Based Access Control
* JEP 309: Dynamic Class-File Constants

    Ok, sounds challenging? do you think you'll be able to turn this around quickly? When do you think you'll have this released.

    Java 11 was out this week, I tried compiling my project with it (upgrading from Java 10) and I think proguard is the only thing not working.

    i think this product is great by the way.

    +1 for Java 11 support. I'm also a big fan of ProGuard so keen to have it working for Java 11. Any feeling for when it will be ready?

    ProGuard 6.1.0 beta2 (available now) supports Java 10, 11 and 12.

    Just tried updating from 6.0.3 to 6.1.0beta2 ready for Java 11 but am hitting the following issue with both Java 10 and 11 (Java 10 was running fine with 6.0.3):

      Thanks for your report. This seems to be the same problem as the recently reported bug #745. Do you also have a statically initialized array of floats or doubles, where one of the elements is an unusual value like NaN, +Inf, or -Inf? Otherwise, can you share a small sample that reproduces the problem?

       

  • Nick Talbot

    Nick Talbot - 2019-04-25

    Thanks Eric. I only found one instance of this (using NaN) in the main code (loads in unit tests which should be excluded anyway). The codebase is nearly 1 million lines so will struggle to pin down the exact issue. As the bug looks like a compara[tor|ble] regression I was hoping it would be easy for you to find... :-)

    I will wait to test the next build after #745 is resolved as there's a good chance it's the same issue.

    Cheers

    Hi Eric. Do you have an approximate timeline for 6.1beta3 and 6.1 GA?

    Thanks!

    I've just tried 6.1.0 on our project. It no longer crashes on Java 10 and also runs fine when we build with OpenJDK 11.0.3

    Thanks!

    I've tried to run it with Java 11, and it does not work. I get the following error:

    ProGuard, version 6.1.1
    Reading program jar [/Users/firetiti/NetBeans/FiReTiTiLiB/dist/FiReTiTiLiB.jar]
    Reading program jar [/Users/firetiti/NetBeans/FiReTiTiLiB/dist/lib/FiReTiTiCoreJava.jar]
    Reading library jar [/Library/Java/JavaVirtualMachines/jdk-11.0.2.jdk/Contents/Home/lib/rt.jar]
    Error: Can't read [/Library/Java/JavaVirtualMachines/jdk-11.0.2.jdk/Contents/Home/lib/rt.jar] (No such file or directory: /Library/Java/JavaVirtualMachines/jdk-11.0.2.jdk/Contents/Home/lib/rt.jar)

    Any idea how to fix it?

     

    • Hendrik Schreiber

      What's your config? You know that JDK 11 does not have a /Contents/Home/lib/rt.jar, right?

       

      • FiReTiTi

        FiReTiTi - 2019-06-27

        Indeed, this file does not exist anymore on Java 11. It seems that it was removed on Java 9.
        I work on a macos with Java 11.
        As the file does not exists anymore, why is proguard looking for it?

          I don't think you've discovered a bug.

          What's your config?

          I.e., how are you calling ProGuard?

           

          • FiReTiTi

            FiReTiTi - 2019-06-28

            I use ProGuard 6.1.1 on Java 11.0.2 on macosX 10.13.6
            I call this command: java -jar ./lib/proguard.jar @MyApp.pro
            It seems that the call to rt.jar comes from my config file that comes from a old proguard version, so I commented the line.
            Thanks.

            I still have too many warnings for basic libraries, so I opened a post on StackOverflow: https://stackoverflow.com/questions/56920082/proguard-does-not-find-basic-packages-and-super-class
