With no mod in the mods folder, new versions of forge (I tried with 1.10.2 and 1.11.2) always crash in the end of loading screen (7/7). I also tried to downgrade my Java 8u112 to Java 8u51 but it didn't work. Instead, Forge 1.8.9 always worked perfectly (and now it still works).
This is the log file (.minecraft\logs\fml-client-latest.log), I really hope u can help me. If u need more details, ask me! (And sorry for my bad english XD)
(In this log i'm using forge 1.10.2 and the last version of java (8u112)
