@sviswa7 please create a CSR request and add link to it in JDK-8256585. This pull request cannot be integrated until the CSR request is approved.

[PaulSandoz]

The documentation Vector.convert and Vector.convertShape needs to be updated to remove specification of in-place conversions, as does the class documentation on Vector. A search for the term in-place should find the relevant locations.

[sviswa7]

Updated documentation to reflect removal of widening and contracting in-place conversions.
