Menelaos Perdikeas updated LANG-885:
------------------------------------
Description:
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?
