boot -d boot/new new -t boot-reframe-10x -n my.example.spa

The resulting application is is unable to find the my.example.spa namespace to run core/main.

NOTE: When running this same template without using java namespace conventions, it will work:

boot -d boot/new new -t boot-reframe-10x -n myexamplespa

Comparing the two projects reveals the issue:

 (deftask development []
   (task-options! cljs {:optimizations :none}
-                 reload {:on-jsload 'my.example.spa/main})
+                 reload {:on-jsload 'myexamplespa.core/main})
   identity)

build.boot is not referencing the full path to core for the Java-style namespaced project.
