[8u] RFR: 8051853: new URI("x/").resolve("..").getSchemeSpecificPart() returns null!

[Alex Kashchenko]

Hi,

Please review the fix to 8051853 for 8u.

Note, the problem is not reproducible in 9+, it was fixed there as a
part of "8146686: Create the schemeSpecificPart for non-opaque URIs
lazily" .

If appendSchemeSpecificPart() doesn't append anything to the specified
buffer, then defineSchemeSpecificPart() returns early and
schemeSpecificPart variable remains null. Proposed change removes
"early return" branch.
