NullPointerException in collectd when evaluating in-memory threshold set

Description

The implementation of Bug2711 causes a NullPointerException, if resources cannot be found. Conditions that create this bug:

1) fresh install w/o a database
2) no pre-existing RRD files

Should be self explanatory. getEntityMap() returns null, and that condition is never handled in the caller. Attached is proof-of-concept diff for fix in 1.7x.

Bill,

Again, thank you very much for catch this.

Fixed on trunk rev.13715.

I applied the patch and added a junit test on ThresholdingVisitorTest to validate that the patch is working.

forgot one:

3) no thresholds configured in a given RRD group to evaluate.
