Subject [lang] IllegalStateException in text.VariableFormatter with "empty" keys.
Date Mon, 25 Jul 2005 16:43:43 GMT
Oliver and all:

The text.VariableFormatter class throws an IllegalStateException for the
template "The ${} jumps over the ${}.":

java.lang.IllegalStateException: Infinite loop in property interpolation
of The ${} jumps over the ${}.: ->
	at
org.apache.commons.lang.text.VariableFormatter.doReplace(VariableFormatt
er.java:380)
	at
org.apache.commons.lang.text.VariableFormatter.replaceObject(VariableFor
matter.java:513)
	at
org.apache.commons.lang.text.VariableFormatterTest.testReplaceNoElement(
VariableFormatterTest.java:230)
	at
org.apache.commons.lang.text.VariableFormatterTest.testReplaceNoEmptyKey
s(VariableFormatterTest.java:263)


I would think that replaceObject should just return the pattern string,
which is what happens when other kinds of malformed patterns are
submitted.

Could you fix this? Or do you think this is really the proper behavior?

Thanks,
Gary
