             Summary: Use Java 7 ProcessBuilder.inheritIO() instead of own ThreadPumper
                 Key: LUCENE-6530
                 URL: https://issues.apache.org/jira/browse/LUCENE-6530
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Uwe Schindler
            Assignee: Uwe Schindler
             Fix For: Trunk, 5.3


In some tests wie spawn separate processes (TestIndexWriterOnJRECrash and Solr's IPTables). To capture stdin/stdout/stderr we spawn several threads that pump those to stdout/stderr.

Since Java 7 there is ProcessBuilder.inheritIO() that does this for us without any additional threads. We should use this instead. Fix is easy, just remove some stuff :-)

I did the same already for my Codec classloader deadlock test, so this is just a followup for the other tests.

Patch is attached and can be committed to trunk and 5.x.
