On windows machine, I am getting the following Exception for while starting the
CodehaleMetricsReporter component
{code:xml}
java.nio.file.InvalidPathException: Illegal char <:> at index 2:

{code}
This is because the we creating RrdDB by passing the path returned by
RrdDef.getPath() method (see
[here|https://github.com/apache/sling-org-apache-sling-commons-metrics-rrd4j/blob/master/src/main/java/org/apache/sling/commons/metrics/rrd4j/impl/RRD4JReporter.java#L374])
which does not return the path correctly and is unreliable as discussed
[here|https://github.com/rrd4j/rrd4j/issues/152] and It is suggested to use
RrdDef.getUri() instead.
Also, while creating the RrdDef with a path RRD4J lib creates an internal
generic URI which again can not be use directly for creating the File or Paths
api as this generic URI could be non-absolute in some cases.
Attaching the test case which should fail on windows machine.
