Package: openjdk-9-jre-headless Version: 9.0.1+11-1 Severity: normal The jrt-fs.jar shipped with this package does not work correctly on Java 8. This is needed by some development tools that run on Java 8 but support development for Java 9, such as IntelliJ IDEA.
A detailed explanation of this issue is on Ubuntu's bug tracker [1]. I have run the test program attached there and found that it fails on the Debian package, too. Additionally, IntelliJ IDEA generates the same exception (which appears in its log file) when trying to use /usr/lib/jvm/java-9-openjdk-amd64 as a JDK.
