> I was trying to train the Treebank Parser with some new data.
> Truth to be told, the data was in poor format. Specifically, instead of "(-RRB- -RRB-)", it contained "( -RRB-)".
> The same for -LRB- constructions.
> Due to this input data, the parsing code was throwing some NullPointerException errors.
> The fixes consist in some supplementary "if()"s, to safeguard against null pointers.
> Fixes are in 3 files, attached as diff. The diff was created by svn, run in the opennlp-tool/.../parser directory.
