The installer (jboss-devstudio-9.1.0.GA-v20160410-1849-B495-installer-eap) adds these components to the user's PATH:

C:\DeveloperPlatform\vagrant\bin;
c:\DeveloperPlatform\cdk\bin;
c:\DeveloperPlatform\vagrant\bin;
c:\DeveloperPlatform\cygwin\bin;

It does not add these to the PATH:
c:\DeveloperPlatform\jdk8\bin;
c:\DeveloperPlatform\developer-studio

If we don't add the JDK and JBDS to the PATH by default, then we should give the user the option to add these during the installation.
