JMeter File Upload with HTTP Put Method Not Working

Question

The idea is to build a sampler in JMeter that will upload a file using the HTTP PUT method. I'm trying to follow the official documentation to specify the entire content body as a file with no parameter name.

• What should happen: The file gets uploaded and the server returns 201: created
• What actually happens:

java.lang.NullPointerException: charsetName at java.lang.String.<init>(Unknown Source) at java.lang.String.<init>(Unknown Source) at org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl.sendPutData(HTTPHC4Impl.java:1067) at org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl.sample(HTTPHC4Impl.java:274) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerProxy.sample(HTTPSamplerProxy.java:62) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1054) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1043) at org.apache.jmeter.threads.JMeterThread.process_sampler(JMeterThread.java:416) at org.apache.jmeter.threads.JMeterThread.run(JMeterThread.java:271) at java.lang.Thread.run(Unknown Source)

This seems to indicate that JMeter has a problem with filling out the body of a request. I can get rid of this error by specifying a parameter with the request, but I want the entire body to be the photo data. Here's the CURL line of what I want accomplished:

curl -u testuser:testpass "http://localhost:8080/photo" -T photo.jpg -H "content-type:image/jpeg"

I've tried setting the content-encoding to UTF-8 as I've seen in one post, but that changed nothing.

I'm running Java 1.7.0 on Windows 7 x64. Nothing of interest gets generated in jmeter.log, and wireshark tells me that JMeter isn't sending the request.

Any ideas? Thanks in advance.

Turns out it was a bug that the nice folks at JMeter were able to fix very quickly: https://issues.apache.org/bugzilla/show_bug.cgi?id=52897

Using the nightly build solved my problem, and by now it has probably made it into the release.
