null
is a valid name
, when getAttributes(null)
is invoked on a Manifest
obtained from a jar file, null
will be returned. While jar files themselves do not allow null
-named attributes, it is possible to invoke getEntries()
on a Manifest
, and on that result, invoke put
with a null key and an arbitrary value. Subsequent invocations of getAttributes(null)
will return the just-put
value. Note that this method does not return the manifest's main attributes; see getMainAttributes()
.
