Why it looks for [http://localhost:9000]

This helped to solve my StackOverFlowError:

StackOverflowError at DefaultInputComponent.equals

I figured it out after attaching my debugger. I have a multi-module Maven project, and in the root POM I had set the property <sonar.projectKey>foo</sonar.projectKey>, which then propagated into the sub-modules, of course. When WorkDirectoriesInitializer.cleanAllWorkingDirs went to recurse through the project, it calculated a key for each module, but it did this by reading the sonar.projectKey property. Because this had the same value for every module, the recursion never completed and the stack…

So I added <sonar.moduleKey>${project.artifactId}</sonar.moduleKey> to the root POM
Thank`s a lot for help!
