Description

I got the following permutaion for the text "Obstruction":
R10ojR9baR8smD7tD6rD5uD4cD3tD2iD1oD0n

When i checked the method decodeShortestEditScript in class opennlp.tools.util.StringUti, which is used to decode the word with permutations.
I got the permIndex variable initialized to 0 and increasing by one to get next permutation letter,
which is gone wrong when the permutation letter has more than 1 digits e.g. in the given permutation R10 mear R and 10, but because of permIndex increating by one, so it is considering as R and 1.
