FYI, planning to drop support for -source/-target/--release 7 from javac in JDK 20

[Joseph D. Darcy]

Hello,

JDK 7 was released in July 2011, over one decade ago. Per the general 
sentiment, but not exact wording, of JEP 182 
(https://openjdk.org/jeps/182), this is about the expected support time 
frame for an argument to javac's -source/-target/--release options in 
subsequent releases. [1]

Therefore, in JDK 20, I think it is time for javac to drop support for 
-source/-target/--release 7. All other supported values would remain as 
such in JDK 20, 8 through 20 inclusive, and there is no implied changes 
to support for 7 in other release trains.

PR for the proposed changes:

[1] Updating JEP 182 to formally account for the six-month release model 
remains as future work.
