-------------------------------
Summary: DefaultThreadPool causes warning when minPoolSize == 0
Key: SLING-6296
URL: https://issues.apache.org/jira/browse/SLING-6296
Project: Sling
Issue Type: Bug
Components: Commons
Affects Versions: Commons Threads 3.2.6
Reporter: Rob Ryan
DefaultThreadPool inappropriately emits a warning when a pool has a min pool
size of 0.
A min pool size of 0 is supported by the downstream ThreadExpiringThreadPool,
and is logically useful when 'empty' is a reasonable size of a pool, e.g. when
no work is apriori expected for the pool.
The code in question is:
// Min pool size
if (this.configuration.getMinPoolSize() < 1) {
this.configuration.setMinPoolSize(1);
this.logger.warn("min-pool-size < 1 for pool \"" + this.name + "\".
Set to 1");
}
The downstream code in ThreadExpiringThreadPool only enforces this value is >=
0.
