Stefan Egli reassigned SLING-7407:
----------------------------------
Assignee: Stefan Egli
> A thread pool with min size 1 uses only 1 thread for processing
> ---------------------------------------------------------------
>
> Key: SLING-7407
> URL: https://issues.apache.org/jira/browse/SLING-7407
> Project: Sling
> Issue Type: Bug
> Components: Commons
> Reporter: Chetan Mehrotra
> Assignee: Stefan Egli
> Priority: Major
> Fix For: Commons Threads 3.2.12
>
>
> If a thread pool is configured like below
> {noformat}
> org.apache.sling.commons.threads.impl.DefaultThreadPool.factory-oak
> name="oak"
> minPoolSize=I"1"
> maxPoolSize=I"5"
> {noformat}
> Then only 1 thread would be used even if multiple jobs are assigned to the
> pool. This happens because of strange behaviour of Java
> [ThreadPoolExecutor|https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ThreadPoolExecutor.html]
> bq. If there are more than corePoolSize but less than maximumPoolSize threads
> running, a new thread will be created only *if the queue is full*
> With unbounded queue used this lead to current behaviour. As a fix Sling
> Thread Pool should adapt such a config
