Hi David, you're correct that the new entries are not of type "C", as the new strings are `static final`. Anyway, the whole reason of this table is to work around the weakness of cdsHeapVerifier, which can sometimes report false positives. The new entries follow the same pattern of the previous entries (which are also wrong ... i.e., `StaticProperty::FILE_ENCODING`)

I have file https://bugs.openjdk.org/browse/JDK-8321940 to improve cdsHeapVerifier. Hopefully I can remove all the entries in cdsHeapVerifier.cpp added by this PR.
