java.net.URISyntaxException. sbt - space in path

I have tried this behavior on sbt 0.13.16 and 1.0.1. Not just for sbtVersion but with even the other sbt commands. I believe the problem is because of the empty space in the path (/C:/Users/Jatin Puri/.sbt/preloaded/)

D:\spark-stemming>sbt sbtVersion
"C:\Users\Jatin Puri\.sbt\preloaded\org.scala-sbt\sbt\"1.0.1"\jars\sbt.jar"

What can be a fix for it? (I can't of-course change the user name). Is this an sbt bug? (I can't believe if it is so, because it is so normal and probable).

Could a fix be to change the default path away from ~/.sbt? But I have not been able to do that. How do we change this default path.
