Ivo Leitão updated SLING-7300:
------------------------------
Description:
Hi,
I'm experiencing severe CPU spikes caused by the reload job in the i18n bundle.
I've uploaded 3 threadumps which I analysed in http://fastthread.io. The
analysis identified a cpu spike in the method scheduleReloadBundles of the
class
https://github.com/apache/sling-org-apache-sling-i18n/blob/master/src/main/java/org/apache/sling/i18n/impl/JcrResourceBundleProvider.java.
This does not happen every time only on some situations. I've experienced this
problem at least on the previous i18n bundle versions. Since there was changes
on the mentioned class I've updated it hopping to get rid of this problem.
Unfortunately I'm experiencing it again :-(
