Problem when try to make a bench of indexing (a dictionary with 120.000 words)

[Leandro]

Hello,

*Sample code:*
SpellChecker spell;
RAMDirectory dram = new RAMDirectory();
Dicionario dic = new Dicionario(); //one implementation of spell.Dictionary
spell= new SpellChecker(dram);
spell.indexDictionary(dic); //indexing...

*Then I got the:*
machine1: Windows XP SP2, Celerom 2.66GHz e 256MB
word: 60.000 (40~53 caracteres cada)
memory alloc: 16 (MB)
time to index: 55108 (ms)

So* I tried with 120.000 words* ... when I run the program ...

*Exception in thread "Thread-1"
