GoogleCodeExporter commented 8 years ago 
SDK/Debugger version:0.3.4
Eclipse version:3.6.1 
Google Chrome/V8 Embedder + version:Google Chrome 18.0.1025.39
OS + version:Windows 7

What steps will reproduce the problem?
1. Start chrome with remote debugging flag
2. Create a new debug configuration in eclipse , select WebkitProtocol and WIP 
backend as Protocol 1.0
3.Start the debugging 

What is the expected result?
  The eclipse plugin connects to google chrome and all scripts are available for debugging

What happens instead?
An internal error occurred during: "Launching New_configuration (1)".
java.lang.NullPointerException

Please provide any additional information below. If possible, attach a
(reduced) test-case.
  This does not happen if "show debugger network communication console" is checked.

The problem is in WipBackendImpl::readHttpResponseContent, where 
browserConnectionLogger.start(); is called on null pointer
