JDK-8224242 - Properties.load fails to throw IAE on malformed unicode in certain circumstances

JDK-8226735 :  
Release Note: Properties Files Containing Malformed Unicode Was Sometimes Misparsed - Closed
Description
A property file like the following should fail to load with an IAE

a=\u0

but if there's a preceding property like this, it might mis-parse instead:

b=\u0123
a=\u0

-> property a erroneously becomes \u0123

Fixing this might mean some properties files that were malformed would go from being silently misparsed to throwing an IllegalArgumentException, so a CSR will be filed.
