GWT Compiler so so slow with 2016.2 release


Hi All,

I work daily on a GWT project with IDEA for a year now. But today I can't work anymore (due to the new IDEA ?)

When running the GWT projet ,  it starts normally till the dev mode is initialized (see below) 

The code server is ready at
Code server started in 27652 ms
waited 14545 ms for code server to finish
Dev Mode initialized. Startup URL:


Then the compilation is very very very very slow, actually I generally stop it after having wait 10 minutes  :-(  -  DevMode is 100% CPU

I had the same issue the day before, and  "File / Invalidate cache and restart" fixes it. But not today !

Any ideas ?
