Uncaught exception: org.apache.commons.httpclient.NoHttpResponseException
-------------------------------------------------------------------------

         Key: WT-296
         URL: http://webtest-community.canoo.com/jira/browse/WT-296
     Project: WebTest
        Type: Bug

    Versions: 2.1    
 Environment: Linux hostname 2.6.17-1.2142_FC4smp #1 SMP Tue Jul 11 22:57:02 EDT 2006 i686 i686 i386 GNU/Linux
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2)
Classic VM (build 1.4.2, J2RE 1.4.2 IBM build cxia32142ifx-20060209 (SR4-1) (JIT enabled: jitc))

- tested on Webtest 2.1, latest snapshot(R_1537) and latest svn snapshot (revision 25937)
- webserver is on localhost

I copied includes/commonVerification.xml and altered it a bit:

<group description="Link integrity check">
	<verifyLinkedContent
		xpath="/html/head/link[@rel='stylesheet']/@href"
		accept="text/css"
		/>
	<verifyLinkedContent
		xpath="//img/@src"
		accept="image/*"
		/>
	<verifyLinkedContent
		xpath="/html/head/link[contains(@rel, 'icon')]/@href"
		accept="image/*"
		/>
	<verifyLinkedContent
		description="Show how to handle alternative mime-types"
		xpath="//script/@src"
		accept="text/javascript;application/x-javascript"
		/>
	<verifyxpath
		description="No empty anchor"
		xpath="not(//a[not(*) and not(text())])"
		/>
	<verifyText
		description="Check for ending &lt;/html&gt; tag"
		text="&lt;/html&gt;"
		/>
</group>

95% of time this commonVerification.xml runs just fine, but the rest 5% I'm getting error on the first step (text/css). Even if I removed first step, the error has just happened on //img/@src which became first step.

The error is as follows:
