Why am I getting the "timeout value is negative" error on LoadTestRunner?

You will get the "Decompression of response failed" error on LoadTestRunner, if your load test delay random factor is > 1.0.

For example, your load test has the following settings:

Strategy: Simple
Delay: 1000
Random: 10.5

If you launch LoadTestRunner from command line, you will get the "timeout value is negative" error in the output:

23:38:53,807 ERROR [SoapUI] An error occurred [timeout value is negative], 
   see error log for details
java.lang.IllegalArgumentException: timeout value is negative
   at java.lang.Thread.sleep(Native Method)
   at com.eviware.soapui.impl.wsdl.loadtest.strategy.SimpleLoadStrategy
      .beforeTestCase(SimpleLoadStrategy.java:81)
   at com.eviware.soapui.impl.wsdl.loadtest.WsdlLoadTestRunner
      $InternalTestRunListener.beforeRun(WsdlLoadTestRunner.java:646)
...

This is really a bug. If the random factor is set too high, LoadTestRunner is actually call Thread.sleep() with a negative value. SoapUI should reject the setting or use a better logic to avoid this error.

So if see the "timeout value is negative" error with LoadTestRunner, you need review your load test settings to make sure Random is in the range of 0.0 and 1.0.
