Hi,

Looking at the com.intellij.openapi.vfs.impl.FilePartNode#myFile(java.lang.Object) method it's impossible that it returned a VirtualFile instance for path parameter as it returns non-null values only when parameter is VirtualFile:

static VirtualFile myFile(@NotNull Object fileOrUrl) {
  return fileOrUrl instanceof VirtualFile ? (VirtualFile)fileOrUrl : null;
}

Maybe two calls were done from different contexts. Could you please provide us with the more information about the issue? Where do you call module.getModuleFile() from?

Please also consider cases mentioned in com.intellij.openapi.module.Module#getModuleFile javadoc. Note this is Internal API and should not be used by 3rd party plugins. See javadoc for alternatives.
