A few days ago I created a tag file for the JDK source files in C:\Program Files\Java\jdk1.8.0_11x\src.
When I try to "Add Tree" with that path and *.java, it quickly completes, but does nothing.
So I quickly just added a couple of the directories worth of *.java files to let me finish what I was working on.
Today, I tried again, and again AddTree does nothing.
I thought maybe it has something to do with the space in the filename.
So I created a symbolic link:
mklink /d C:\src\java C:\Program Files\Java\jdk1.8.0_11x
Then I used that as the path in AddTree for that tag file.
Slick complains over and over about an error in the status line and very quickly consumes *ALL* system memory.
I had to repro it a couple of times before I thought to attach a debugger ahead of time, and break into the process before it crashes my system again.
