I am running the code above because of 

Java 11 Considerations

• The following - -add-opens switches need to be added in order to prevent related reflection access WARNING messages in the stdout.log
• Additionally, you need to make use of the -XX:+UseParallelGC switch in order to mitigate any potential performance issues.

When I access http://localhost:4502/  I am redirected always to http://localhost:4502/libs/granite/core/content/login.html?resource=%2Fsites&$$login$$=%24%24login%24%24&j_reason=unknown&j_reason_code=unknown 

even if I access http://localhost:4502/sites  I always redirect to 

http://localhost:4502/libs/granite/core/content/login.html?resource=%2Fsites&$$login$$=%24%24login%24%24&j_reason=unknown&j_reason_code=unknown 

and I see 

1. How to fix this error ?

2. How to run the command so I can see the site ?
