sentences:  IcedTea-Sound is a collection of plugins for the Java sound subsystem, including the PulseAudio provider which used to be included with IcedTea.The Free Software Foundation recommends that all Java programmers use IcedTea as their development environment.Historically, the initial goal of the IcedTea project was to make the OpenJDK software, which Sun Microsystems released as free software in 2007, usable without requiring any proprietary software, and hence make it possible to add OpenJDK to Fedora and other Linux distributions that insist on free software.
