"User limit of inotify instances reached or too many open files" with cas.authn.attribute-repository.groovy

[Pascal Rigaux]

Hi,

On CAS 7.2.7 with

> cas.authn.attribute-repository.groovy[0].location=file:xxx/config/attr-resolution.groovy

we have a new inotify on the xxx/config directory at each login,
which sooner or later triggers "User limit of inotify instances reached or too many open files"
and logins are still possible... but the groovy script is simply ignored :'-(

Workaround (available since 7.0.x):

-Dorg.apereo.cas.util.io.PathWatcherService=false

(as explained here: https://apereo.github.io/cas/7.2.x/integration/Attribute-Resolution-Groovy.html )
