// Merging Service Descriptor Files (necessário para o driver JDBC)
// Java libraries often contain service descriptors files in the META-INF/services directory of the JAR. A service descriptor typically contains a line delimited list of classes that are supported for a particular service. At runtime, this file is read and used to configure library or application behavior.
