Peter Dillinger 7da8c067a2 Avoid heading tags in javadocs; fix EnvironmentTest (#6208)
Summary:
Should fix Travis build error that randomly showed up upon
using Java 13 version of javadoc.

    AdvancedColumnFamilyOptionsInterface.java:257: error:
      unexpected heading used: <H2>, compared to implicit preceding heading: <H3>

According to this reference https://bugs.openjdk.java.net/browse/JDK-8220379
it should work to start at h4, but that didn't work, so avoiding
headings should be fine.

Also fix Java EnvironmentTest for JDK13.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/6208

Test Plan: Travis run on PR (don't have Java 13 handy)
