----------------------------------------------------------
It seems that not all the characters could be used in the hostname:
https://stackoverflow.com/questions/28568188/java-net-uri-get-host-with-underscores.
For example, underscores could not be used in the hostname. Currently, the
failed test case generates the path randomly and it may happen that it
generates a path which is not valid.
So there are the following ways for this problem:
- Exclude all the invalid characters when generating the hostname (This means
that we need to figure out all the characters which are not supported)
- Add some retries when generating the path util when we got a valid path
- Use a fixed hostname when generating the path
Personally I lean to 2), what do you think?
