Version 3.5+ - certain strings throwing NumberFormatException in REPL

[omriAckley]

In the REPL, if you evaluate a string starting with a digit, that is followed at some point by a non-digit non-bracket, which is followed at some point by a forward slash, a NumberFormatException is thrown. However, this exception does not seem to halt anything, because it ultimately returns the correct result.

If it helps to conceptualize, I think the following regex would match any strings for the bug occurs: #"[0-9]+[^{}]+/.*"

This bug does not occur if the string is produce through an expression, rather than writing it by hand.

For example:

user> "5a/"
NumberFormatException Invalid number: 5a  clojure.lang.LispReader.readNumber (LispReader.java:253)
RuntimeException Unmatched delimiter: )  clojure.lang.Util.runtimeException (Util.java:156)
RuntimeException Unmatched delimiter: )  clojure.lang.Util.runtimeException (Util.java:156)
RuntimeException Unmatched delimiter: )  clojure.lang.Util.runtimeException (Util.java:156)
RuntimeException Unmatched delimiter: )  clojure.lang.Util.runtimeException (Util.java:156)
RuntimeException Unmatched delimiter: )  clojure.lang.Util.runtimeException (Util.java:156)
=> "5a/"

user> (str 5 'a '/)
=> "5a/"
