jdeps intends to report an error if there are multiple versions of the same class being parsed. module-info.class should be excluded from such detection.
This patch also fixes a data race in `VersionHelper::set` and also unwraps the `ExecutionException` when FutureTask of parsing the classes throws an exception to report `MultiReleaseException` properly. ------------- Commit messages: - add comment to the test - JDK-8277165: jdeps cannot handle 2 jars that put module-info.class in a different versioned directory Changes: https://git.openjdk.java.net/jdk/pull/6530/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=6530&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8277165 Stats: 301 lines in 11 files changed: 288 ins; 6 del; 7 mod Patch: https://git.openjdk.java.net/jdk/pull/6530.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/6530/head:pull/6530 PR: https://git.openjdk.java.net/jdk/pull/6530
