Fixes "java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference"
Within
getInputStream(), there is a conditional in which.equals()is invoked onu.getScheme().If
u.getScheme()isnullas can sometimes be the case, this will break functions such asFilesystem.readFile()by breaking thegetInputStream()function.This fix involves first checking that
u.getScheme() != nullwithin the conditional.
