If the current working directory contains spaces, gremlin.sh does not handle it properly when launching the console, and the JVM will search for an incorrect main class and fail.
For example if I simply rename the standard console distribution directory to
foo bar
:foo bar/ $ bin/gremlin.sh
Error: Could not find or load main class bar
Caused by: java.lang.ClassNotFoundException: bar
Added quotations around directory path in order to ensure spaces in directory name are not considered two separate strings
