Burn bootloader blocks IDE until it is completed #2009
Description
Tested using the ide-1.5.x branch from git.
This is probably because the bootloader process does not happen in a separate thread. There is an attempt to do this by using SwingUtilities.invokeLater, but that doesn't spawn a new thread, it just runs the given function later in the event dispatching thread, which still locks up the GUI thread for as long as the function runs.
The proper fix this is to use an actual thread, but this should probably be combined by integrating the burn bootloader process into the verify/upload process (which should be simplified a lot - there's a lot of (unneeded) processing abstractions in there).
