It seems the value was not propagated correctly. Try adding this patch:
diff --git a/make/CompileJavaModules.gmk b/make/CompileJavaModules.gmk
--- a/make/CompileJavaModules.gmk
+++ b/make/CompileJavaModules.gmk
@@ -481,7 +481,7 @@
      $1_CLASSPATH := $$($1_CLASSPATH) $$(addprefix 
    $1_CLASSPATH := $$(subst $$(SPACE),$$(PATH_SEP),$$($1_CLASSPATH))
-  $1_JAVAC_FLAGS := -bootclasspath "$$($1_CLASSPATH)"
+  $1_JAVAC_FLAGS := -bootclasspath "$$($1_CLASSPATH)" 

    $$(eval $$(call SetupJavaCompilation,$1, \
        SETUP := $$(if $$($1_SETUP), $$($1_SETUP), GENERATE_JDKBYTECODE), \

Now Erik's suggestion should work.

Also, if the syntax is still in flux, I'd like to recommend a solution 
without semicolon, since that is interpreted as a command line separator 
in the unix shell world, and it's always a lot of hassle if you need to 
propagate those. Commas are much simpler. :)
