I debugged the problem that I reported earlier (generating incorrect paths in deps.js) and looks like it is due to a bug in com.google.javascript.jscomp.deps.PathUtil.isAbsolute. It is implemented by simply checking that the path starts by a forward slash which of course is incorrect under Windows.
So what is the procedure when the bug is in an external dependency? It is not as if it is a single call that can be avoided. PathUtil.isAbsolute is called a few levels below in the call stack from the com.google.javascript.jscomp.deps.DepsGenerator.computeDependencyCalls, which is supposed to compute and return the correct text for dependencies file. I will debug this further but just wanted to understand if I should I try to work around the external bug when I meet one or I need to try something else? Tigran. P.S. Did anyone actually try running FalconJX on Windows or everybody is developing on a Mac?
