Play/BoneCP message "releaseHelperThreads has been deprecated"

Question

Does anyone know if the following message obtained when starting a Play 2.2 app is important or not?

WARN  - releaseHelperThreads has been deprecated 
  -- it tends to slow down your application more.

I cannot find this setting anywhere, and most references to the message are just log output. I'm assuming it is a bonecp setting, but can't see where play is setting it, if, in fact, it is doing so.

Answer 1

Judging from this, play is setting releaseHelperThreads to 0 (disabled?), but as the setting is deprecated, any call to the setter produces the warning message. If I understood the code comments correctly, the message will disappear once Play moves to BoneCP 0.8.0 or beyond. Bottom line: nothing to worry about.

Answer 2

I think you are using

BoneCPConfig config = new BoneCPConfig();
config.setReleaseHelperThreads(1);

Or

< property name="releaseHelperThreads" value="1" />

setReleaseHelperThreads method is deprecated in version 0.8.0.RELEASE, that's why it showing "releaseHelperThreads has been deprecated -- it tends to slow down your application more." warning.

This setReleaseHelperThreads(1) method is used to sets number of helper threads to create that will handle releasing a connection.
