Description Sebb 2014-03-05 22:28:40 UTC

If jmeter.httpclient.strict_rfc2616=true and the Location: header consists of just a path (no protocol/host) then an NPE is generated:

java.lang.NullPointerException
	at org.apache.jorphan.util.JOrphanUtils.replaceAllChars(JOrphanUtils.java:264)
	at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.encodeSpaces(HTTPSamplerBase.java:1332)

	at java.lang.Thread.run(Thread.java:744)

This is because it's not possible to create a URL without a protocol, so the code skips setting the result redirectlocation. This eventually causes the NPE.

Seems to have been caused by http://svn.apache.org/r1550547 (Bug 55717)

A work-round is to save the unsantised location header in case the exception path is taken
