Exception when looking up particular strings in MapDoubleArray

[amake]

The following produces an ArrayIndexOutOfBoundsException:

MapPatriciaTrie<Object> mpt = new MapPatriciaTrie<>();
mpt.insert("FOO");
mpt.get("F");
mpt.get("f");

MapDoubleArray<Object> mda = new MapDoubleArray<>(mpt);
mda.get("F");
mda.get("f"); // exception here

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1
    at org.trie4j.bv.BytesRank1OnlySuccinctBitVector.isOne(BytesRank1OnlySuccinctBitVector.java:90)
    at org.trie4j.bv.BytesRank1OnlySuccinctBitVector.get(BytesRank1OnlySuccinctBitVector.java:80)
    at org.trie4j.doublearray.DoubleArray.getTermId(DoubleArray.java:243)
    at org.trie4j.AbstractTermIdMapTrie.get(AbstractTermIdMapTrie.java:141)

I would expect this to simply return null rather than throw an exception. My use case is (natural-language) dictionary lookup with mixed-case keys.

Thanks Aaron,

Which version did you use? I tested your code with 0.9.2 and got no error (mda.get("f") returns null).

My apologies, it was 0.9.1. I updated to 0.9.2 and the issue seems to be resolved.

Thanks!
