Sun's corporate image is grounded in its embrace of open-source software and some components of JavaFX, including the JavaFX compiler and elements of graphic libraries, are now available under the GPLv2 open-source license, according to the official JavaFX .
But other key components are still proprietary. Sun is now working to change this, according to a recent blog by Jeet Kaul, vice president of the Client Software Group.
"There are some dependencies on licensed code that cannot be open sourced. We are working towards decoupling the dependencies so that the non-proprietary portions can be open sourced," Kaul wrote. "We will put the core runtime out in the open over time."
Kaul did not spell out the nature of the dependencies. A spokesman for Sun did not immediately respond to a request for more information Tuesday.
Sun will also publish specifications for new file formats associated with JavaFX, "shortly," Kaul said.
