---------------------------------------
Patches welcome! :-)
> Shutdown thread pools in test cases
> -----------------------------------
>
> Key: LANG-1091
> URL: https://issues.apache.org/jira/browse/LANG-1091
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.builder.*, lang.concurrent.*
> Affects Versions: 4.0
> Environment: Linux, JDK 7
> Reporter: Jesper Öqvist
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> The tests, in for example
> org.apache.commons.lang3.builder.ToStringStyleConcurrencyTest, create thread
> pools which are not shut down properly, leading to idle worker threads that
> can prevent the JVM from shutting down properly.
> Suggested fix: shutdown() on the thread pool where a call to shutdown or
> shutdownNow is missing.
> Affected classes (these were the ones I could find easily, I may have missed
> some):
> * org.apache.commons.lang3.builder.ReflectionToStringStyleConcurrencyTest
> * org.apache.commons.lang3.builder.ToStringStyleConcurrencyTest
> * org.apache.commons.lang3.concurrent.CallableBackgroundInitializerTest
