Not a native English speaker, so my feeling might be incorrect. Will someone interpret this as that System.getProperty() will return a cached value?
I would say “Although getProperty() always returns the last value set by setProperty() (I assume this is the current behavior), it is not uncommon that consumers of a system property may read it once and cache the value it for later use, which means setting the property <strong>may not have the desired effect</strong>”. I also don’t think it’s worth listing the 4 property names in the spec. Quite some other system properties are also cached. Listing them there could further suggests that calling getProperty() on them will return the cached value.
