thanks @adamfarley - I have approved it as it partially addresses #6430, to fully close it, you could also deal with the duplicate entry of sun/security/ssl/X509TrustManagerImpl/distrust/Symantec.java mentioned in that issue as well. Ignore, early morning review (I misremembered the 2nd entry, and thought we'd need to capture a comment on the 2nd issue that Symantec was excluded under), and also thought there'd be a keyword "closes" or "fixes". Thanks for working through these issues @adamfarley!
