Make java client lib accept same connection strings as psql

Hi PostgreSQL Hackers,
I've run into something confusing. The psql command accepts
connection strings of the form:

postgresql://user1:pass1(at)localhost:5432/db1?sslmode=require

But passing this string to the java client library (with a "jdbc:"
prefix) fails. See the exception and stack trace below. According to
the docs https://jdbc.postgresql.org/documentation/80/connect.html ,
the java client library accepts connection strings with this form:

postgresql://localhost:5432/db1?user=user1&password=pass1&ssl=true

How about making the Java client library accept the same connection
strings as psql and other command-line tools? That would make
PostgreSQL easier to use and increase its popularity.

Sincerely,
Michael
