Subject [jira] [Created] (ACCUMULO-2429) Shell does not clean up JLine ConsoleReader, leaks threads

--------------------------------------

             Summary: Shell does not clean up JLine ConsoleReader, leaks threads
                 Key: ACCUMULO-2429
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2429
             Project: Accumulo
          Issue Type: Bug
          Components: shell
    Affects Versions: 1.5.1, 1.4.4
            Reporter: Bill Havanki
            Assignee: Bill Havanki


The shell uses the JLine {{ConsoleReader}} class. That class spawns a thread on construction
(tsk-tsk) for its internal non-blocking input stream representation. If the {{ConsoleReader}}
is not shut down properly, the thread keeps running. This is particularly a problem when running
{{ShellServerIT}} under 1.6 and later; the JVM can run out of memory to allocate threads and
fail the test.
