Apache Ant Core 1.10.14 · org.apache.tools.ant.util.KeepAliveOutputStream

Class that can be used to wrap System.out and System.err without getting anxious about any client closing the stream.

In code-language it means that it is not necessary to do:

if (out != System.out && out != System.err) {
  out.close();
}
