Errors when running against Solr 4.5.1 + patch

[Javier Méndez]

I got the following errors when running against Solr 4.5.1

[Thread-693]|ERROR|[com.plugtree.solrmeter.model.statistic.CacheHistoryStatistic]|16:18:06,577 | Could not update statistic
com.plugtree.solrmeter.model.exception.StatisticConnectionException: java.lang.ClassCastException: java.lang.Float cannot be cast to java.lang.String

Re-built Solrmeter to the latest version and got:

Exception in thread "Thread-611" java.lang.NullPointerException
    at com.plugtree.solrmeter.model.operation.QueryOperation.execute(QueryOperation.java:54)

    at com.plugtree.solrmeter.model.operation.RandomOperationExecutorThread.run(RandomOperationExecutorThread.java:62)

Seems is not handling grouped responses correctly.

I did some small modifications to prevent such errors, see patch attached. Hope it helps!

Hi Javier, thanks for the patch. Seems like the problem is the same one described in issue 113, correct? You also added a couple of unrelated changes in the patch, why did you need to change those, did you find another bug?

Yes, is the same issue described on 113. And the solution there actually makes more sense! Use the matched docs instead of counting the groups. To be honest I didn't spend too much time looking at existing issues.

The other problem I found was with the first exception in my original message. Class cast exception when reading cached data. For some reason hitratio and cumulative_hitratio are now floats, not Strings.

Thank you
