Unable to start sonarqube java.net.ConnectException

Hello @sachinmukherjee,

A user ran into this issue in the past (SonarQube 6.7.5 startup failure: Failed to connect to the Wrapper at port 0 - #8 by shivdewangan). He was using a network drive which is not supported.
Any chance that you are doing the same here?

Note that the error:

comes from the underlying component SQ uses (Tanuki Wrapper) which apparently fails to instantiate a JVM to launch other SQ processes.
