Luke Cwik commented on BEAM-5919: --------------------------------- Note that https://blog.codefx.org/tools/multi-release-jars-multiple-java-versions/ describes the structure of Java 9+ multi-release jars: > Build breaks when including Multi-release Jars > ---------------------------------------------- > > Key: BEAM-5919 > URL: https://issues.apache.org/jira/browse/BEAM-5919 > Project: Beam > Issue Type: Bug > Components: build-system > Affects Versions: 2.8.0 > Reporter: Ismaël Mejía > Assignee: Luke Cwik > Priority: Minor > Attachments: logjava9jarissue.txt > > Time Spent: 1h 40m > Remaining Estimate: 0h > > As part of BEAM-5891 there is a reported problem in the build system with > jars that contain multiple versions of the classes (this is a feature > introduced in Java 9). This should not be a problem when the main classes are > still Java 8 compatible as it is the case for byte buddy. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
