Hi all,

I worked on BEAM-1544 <https://issues.apache.org/jira/browse/BEAM-1544> for
a while, which is to bring Java cross-JDK test to Jenkins, and finished
this task recently. Now, there is a post commit Jenkins build running on
three different Java JDK versions (Jenkins link
<https://builds.apache.org/job/beam_PostCommit_Java_JDK_Versions_Test/>)! This
test has already caught several issues, and I hope it continues to provide
quick insights into the functionality of Beam across JDK versions.

Here are some details:

   - Current JDK versions used in the test:
   - JDK 1.7
      - OpenJDK 7
      - OpenJDK 8
   - Same coverage as beam_PostCommit_Java_MavenInstall.
   - Scheduled to run every 6 hours, concurrently.

Known issues:

   - PR-3320 <https://github.com/apache/beam/pull/3320> (just merged):
   Compiling error in Flink runners
   - BEAM-2425 <https://issues.apache.org/jira/browse/BEAM-2425>: Package
   does not exit when building beam-sdks-java-javadoc in JDK1.7
   - BEAM-2322 <https://issues.apache.org/jira/browse/BEAM-2322>, BEAM-2323
   <https://issues.apache.org/jira/browse/BEAM-2323>, BEAM-2324
   <https://issues.apache.org/jira/browse/BEAM-2324>: some Apex tests
   failed if project directory contains space
