PROBLEMA NA ATUALIZAÇÃO PI JDBC 2017-2018

Problemas encontrados na atualização da versão 2017 para 2018. Quando a biblioteca de conexão tenta acessar tal funcionalidade ocorre a excessão "PreparedStatement#addBatch() is not implemented yet". Problema similar ocorre com o uso da opção setReadOnly que deixou de ser suportada na versão 2018 do driver. Quando o método abaixo é invocado uma excessão é lançada o que causa problemas na nossa implementação. Talvez uma solução seja adicionar uma mensagem de warning como a realizada no método setTransactionIsolation. public void setReadOnly(boolean readOnly) throws SQLException {     throw new SQLFeatureNotSupportedException("setReadOnly() is not supported by PI JDBC Driver."); } public void setTransactionIsolation(int level) throws SQLException {     if (this.isClosed()) {         throw new SQLException("Connection is closed.");     } else if (level != 1 && level != 2 && level != 4 && level != 8) {         throw new SQLException("Invalid level.");     } else {         if (this.getLogger() != null) {             this.getLogger().warning("Transactions are not supported by PI JDBC Driver.");         }     } }
