uncommented firstSearcher in solrconfig.xml, got exception
(I don't know if this is a solr-user or solr-dev matter.)
By uncommenting firstSearcher event in solrconfig.xml in trunk
(downloaded from hudson Sept.16), as in:
<listener event="firstSearcher" class="solr.QuerySenderListener">
<arr name="queries">
<lst> <str name="q">fast_warm</str> <str name="start">0</str>
<str name="rows">10</str> </lst>
</arr>
</listener>
I got this exception:
20-set-2007 21.10.14 org.apache.solr.core.SolrCore parseListener
INFO: Searching for listeners: //listener[@event="firstSearcher"]
java.lang.InstantiationException: org.apache.solr.core.QuerySenderListener
at java.lang.Class.newInstance0(Unknown Source)
at java.lang.Class.newInstance(Unknown Source)
at org.apache.solr.core.Config.newInstance(Config.java:304)
[...]
This issue is easily reproducible by using the example directory, just
uncomment firstSearcher and/or newSearcher event in the sorlconfig.xml,
and launch solr.

OK, it looks like the recent modification to get rid of the single
static solr core introduced
a constructor that takes a SolrCore. This broke the initialization
code that does a simple clazz.newInstance();

Confirmed.
I wonder if this is caused by the recent multi-core refactoring?
It seems like a null pointer exception happens at
Config config = core.getSolrConfig();
Assuming that this is the cause of the failed instantiation and not a
result of it?
