[jira] [Resolved] (ACCUMULO-2429) 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
> Reporter: Bill Havanki

> Labels: memory-leak, shell, threads
> Fix For: 1.6.0, 1.7.0

>
> 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.
