The template uses "#XPATCH#" but XPATCH is a series of options separated by whitespace. The quotes will group these options into a single -Xpatch option for java.compiler, with a weird and funky, non existent value.

Simplest solution is to remove the quotes, and not use paths with whitespace in filenames; allowing paths with whitespace in filenames will be a bit harder, and will require quoting each -Xpatch option, or else escaping any whitespace in filenames
