Subject [jira] [Created] (LANG-885) Apache commons StringEscapeUtils.unescapeJava(“\\”) returns “”
Date Mon, 15 Apr 2013 16:36:15 GMT
Menelaos Perdikeas created LANG-885:
---------------------------------------

             Summary: Apache commons StringEscapeUtils.unescapeJava(“\\”) returns “”
                 Key: LANG-885
                 URL: https://issues.apache.org/jira/browse/LANG-885
             Project: Commons Lang
          Issue Type: Bug
    Affects Versions: 3.1
         Environment: Linux 3.2.0-40-generic-pae #64-Ubuntu SMP i686 athlon i386 GNU/Linux
            Reporter: Menelaos Perdikeas
            Priority: Minor




The following code:

final String INVALID_ESCAPE="\\";
System.out.println(String.format("'%s' -> '%s'", INVALID_ESCAPE, 
    StringEscapeUtils.unescapeJava(INVALID_ESCAPE)));

... produces:

'\' -> ''

on the console. Since '\' is not a valid escape I would expect an Exception at runtime. Am
I missing anything?
