Henri Yandell commented on LANG-885:
------------------------------------
Note that we do have a TODO statement:
// TODO: throw "illegal character: \92" as an Exception if a \ on the end of
the Java (as per the compiler)?
> 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:
> {code:title=foo.java|borderStyle=solid}
> final String INVALID_ESCAPE="\\";
> System.out.println(String.format("'%s' -> '%s'", INVALID_ESCAPE,
> StringEscapeUtils.unescapeJava(INVALID_ESCAPE)));
> {code}
> ... produces:
> '\' -> ''
> on the console. Since '\' is not a valid escape I would expect an Exception
> at runtime. Am I missing anything?
