[7u40] Request for phase 2 approval for CR 8017566

[Seán Coffey]

I'd like to port this fix to the 7u40 release. This fix (backout of 
8000450) was already pushed to jdk8. The change is identical for 7u. 
Reviewed by Mandy. I'd welcome a 2nd reviewer for the purpose of phase 2 
approval. JPRT tests run with results as expected. JCK issues also resolved.
