This commit fixes configuration and runtime issues with the Java 17 test
CI variant and removes the Java 11 one, now that Spring Framework 5.3.x
is in maintenance mode.
Prior to this commit, the addDefaultHttpMessageConverters() method in
WebMvcConfigurationSupport caught Throwable for SourceHttpMessageConverter
instantiation; whereas, the rest of the code base correctly catches Error
for SourceHttpMessageConverter instantiation (to handle errors such as
NoClassDefFoundError).
Throwable should not be caught since it can mask other categories of
failures (such as configuration errors).
This commit therefore switches to catching Error for SourceHttpMessageConverter
instantiation in WebMvcConfigurationSupport.

SocketUtils was officially deprecated in 5.3.16 (gh-28052) and removed
in 6.0 M3 (gh-28054); however, there is still need for a subset of this
functionality in integration tests for testing scenarios in which it is
not possible for the system under test to select its own random port
(or rely on the operating system to provide an ephemeral port).
This commit therefore introduces a scaled down version in the
spring-test module called TestSocketUtils which supports retrieval of a
single TCP port.

- English names can be used in "month" field instead of "day-of-month"
field in cron expressions in integration.adoc

Prior to this commit, ternary and Elvis expressions enclosed in
parentheses (to account for operator precedence) were properly parsed
and evaluated; however, the corresponding toStringAST() implementations
did not enclose the results in parentheses. Consequently, the string
representation of the ASTs did not reflect the original semantics of
such expressions.
For example, given "(4 % 2 == 0 ? 1 : 0) * 10" as the expression to
parse and evaluate, the result of toStringAST() was previously
"(((4 % 2) == 0) ? 1 : 0 * 10)" instead of
"((((4 % 2) == 0) ? 1 : 0) * 10)", implying that 0 should be multiplied
by 10 instead of multiplying the result of the ternary expression by 10.
This commit addresses this by ensuring that SpEL ternary and Elvis
expressions are enclosed in parentheses in toStringAST().

As a follow up to 332b25b680, this commit consistently avoids the use of
reflection for annotation attribute method invocations.
