enabling java assertions in the tests

While testing LUCENE-866 I realized that Java assertions
are disabled when *I* run 'ant test'.

Others did have the assertion executed and causing that
NPE. So I am not sure if this is general problem or only
a Windows one.

Compile wise we are ok, having "-source 1.4".
At runtime, assertions can be enabled by running "java
-ea".
Using ant, setting "ANT_ARGS=-ea" is supposed to
have the
same effect, but it doesn't, at least not for me.

Adding:
     <assertions>
         <enable/>
     </assertions>
to the <junit> task would enable assertions during
tests
regardless of ANT_OPTS variable (and hopefully on all OSs).

Anyone sees a problem with adding this?

Btw, I think we can/should use Java asserts more (there are
currently only 4 active asserts under trunk/java).

Indeed, see below. I'm running Linux and java 1.6.0.

My common-build.xml has this added in the junit task:

      <assertions>
        <enable
package="org.apache.lucene"/>
      </assertions>
