Problema com parsing de código

[guerraem]

Esse erro veio de um dos alunos que tentou usar o Neutrino no laboratóro:

Creio estar resolvido. Faltava o parser tratar Modifiers em VariableDeclarationStatement. As declarações de variáveis com "final" geravam esse erro de sintaxe.

É difícil de testar aqui o código exatamente como está, pois não tenho todas essas classes que o código depende, isso gera vários erros no parsing. O problema dos modifiers está resolvido.

Vou baixar e testar aqui, se não der nada errado marco como resolvido.
