arduino-builder misbehaves with links (junctions) on Windows

I develop a large project that is split into libraries. I used to make links (junctions) from development directories to the Arduino Libraries directory. That allows for quick edit-and-test cycles, as the changes are in effect immediately. This worked good in 1.x; this semi-worked in 1.6.5 and seems to be completely broken in 1.6.6 (maybe, somehow related to Java 8 or new library discovery): IDE just doesn't "see" the linked libraries.

Furthermore, uninstaller deletes not the links, but traverses and deletes all the files which can be very disasterous.
