Further investigation shows:
g! type bundles
bundles is Bundle[] context:bundles()
true
g! type headers
headers is void felix:headers(Bundle[])
true
// so bundles appears to return the Bundle[] type required by the headers
command
g! b = (bundles)

-----------------
Bundle-Description = This bundle is system specific; it implements various
system services.
// etc
Note: https://issues.apache.org/jira/browse/FELIX-2337 is also related to
this, as
x = command args
can set x to an array[], while
x = (command args)
will always convert the result to an ArrayList.
ArrayLists are undoubtedly more "useful", but I wonder whether array[]
results should be automatically converted to ArrayLists, rather than just
coerced as needed, like any other type.
