      Description

      Agents launched under openjdk9 appear to be incompatible with masters running openjdk 7 or 8.

      At the end of a Execute Shell step, an exception is thrown in what appears to be the process cleanup code. In the example below, the Execute Shell indicated a failure, but the issue occurs even if Execute Shell succeeds.

      <... normal test execution...>
      Build step 'Execute shell' marked build as failure
      FATAL: Remote call on <redacted remote name> failed
      java.io.IOException: Remote call on <redacted remote name> failed
