PatternSyntaxException with invalid MapCSS

[naoliv]

I was testing this (wrong) test:

*[/_{1,2,3}$/] {
        throwError: tr("chave inválida: {0}", "{0.key}");
}

And JOSM gave an error:

ERRO: java.util.regex.PatternSyntaxException: Unclosed counted closure near index 5
_{1,2,3}$
     ^
java.util.regex.PatternSyntaxException: Unclosed counted closure near index 5
