I understand the situation for supporting Java.

Do you mean 42.3 would be released between January and March in "2021"?

More or less. We don't have a fixed schedule. Please don't consider these dates to be "cast in stone"

Hi Ryohei Takahashi,

I believe, the intention is to drop Java 6 and Java 7 support at the same time.
Note: release/42.2 branch would still be there, and we would be able to release fixes if needed (e.g. for security
issues).

Note: the recent releases are still 42.2.x as there are security/data integrity issues which we are not comfortable
to keep in the "latest released versions for Java 6/7"

The intention is to keep support Java 6 and Java 7 for pgjdbc 42.2.x, while pgjdbc 42.3.x would support Java 8+ only.

I guess we would release 42.3 in Q1 2020, then the development in 42.2 would cease.

In practice, there's no funding for pgjdbc development :(, so the policy to support Java X is moot.
One more thing is I can't install Java 6 on my local machine (which runs macOS 10.14), so it is hard for me even to
validate
if the code compiles with Java 6.

The next LTS Java would be Java 17 in September 2021, and I believe that is the earliest date to consider drop Java 8
supportin pgjdbc.
 
The next Java LTS would be in 2024, and it might be the time we drop Java 8 and switch to Java 11+, however, that is a
wildguess rather than an exact plan.
