It sounds like when you use the GUI Builder that some IntelliJ Byte Instrumentation/code gets inserted into your program.
"Unique Byte-code instrumentation technics allow you to get rid of complicated Swing code in your Java sources. "
Does this put JetBrains proprietary intellectual property into my program?
How does this affected the licensing of the resulting program (my program)? Can I make my program open source (GPL or BSD) and can I sell it commercially?
