Description

When specifying a field name that starts with a digit (or digits) in the "fl" parameter solr returns both the field name and field value as the those digits. For example, using nightly build "apache-solr-4.0-2012-04-24_08-27-47" I run:

java -jar start.jar
and
java -jar post.jar solr.xml monitor.xml

If I then add a field to the field list that starts with a digit ( localhost:8983/solr/select?q=:&fl=24 ) the results look like:
...
<doc>
<long name="24">24</long>
</doc>
...

if I try fl=24_7 it looks like everything after the underscore is truncated
...
<doc>
<long name="24">24</long>
</doc>
...

and if I try fl=3test it looks like everything after the last digit is truncated
...
<doc>
<long name="3">3</long>
</doc>
...

If I have an actual value for that field (say I've indexed 24_7 to be "true" ) I get back that value as well as the behavior above.
...
<doc>
<bool name="24_7">true</bool>
<long name="24">24</long>
</doc>
