8051627: Invariants about java.net.URI resolve and relativize are wrong

[tkiriyama]

The current documentation of URI class describes relationship between resolve and relativize methods as follows.

For any two normalized URIs u and v,
    u.relativize(u.resolve(v)).equals(v) and
    u.resolve(u.relativize(v)).equals(v) .

However, there are some cases where this relationship is not true. For example, when u and v are "http://a/b" and "c/d", respectively, both u.relativize(u.resolve(v)) and u.resolve(u.relativize(v)) equal to "http://a/c/d" not "c/d". The documentation should be updated to avoid confusion by describing the relationship between resolve nd relativize methods under certain conditions of the URI. Note that these conditions are sufficient but not necessary for the statement.

@dfuch Thank you for your review and suggestions.

A colon ':' may be more appropriate than a period '.' at the end of this sentence: I'd suggest:

You’re right. I changed to use a colon.

Could you update the UriTest with some examples and counter-examples to validate this claim?

I added tests in URI/Test.java.
The tests include testing if the resolve-relativize relationship stand when the two URIs meet the condition of the modified javadoc.
The tests also include testing if the relationship does not stand when the two specific URIs which meets the condition of the original javadoc are given. These URIs are excluded by the condition of the modiied javadoc.

Hi @tkiriyama sorry for taking so long to get back to you. I had a look at the CSR - and fixed a few missing fields, and added myself as reviewer. Please move its state to "Proposed" to get this moving further.

@dfuch Thank you for your reply. I moved CSR's status to "PROPOSED". Please review it.
