Prior to this commit it was impossible to have an individual
constructor argument in a @Nested (i.e., inner) test class injected via
@Autowired, @Qualifier, or @Value.

This is due to a bug in javac on JDK versions prior to 9, whereby
annotation lookups performed directly via the
java.lang.reflect.Parameter API fail for inner class constructors.

Specifically, the parameter annotations array in the compiled byte code
for the user's test class excludes an entry for the implicit enclosing
instance parameter for an inner class constructor.

This commit introduces a workaround in ParameterAutowireUtils for this
off-by-one error by transparently looking up annotations on the
preceding Parameter object (i.e., index - 1). In addition, this commit
relies on the change recently introduced in MethodParameter in order to
compensate for the same JDK bug (see SPR-16652).

In my opinion, we should parse ":{x}" style parameter as "x" is parameter using "NamedParameterUtils.parseSqlStatement",
so the condition "j - i > 2" is the correct condition, not "j - i > 3", because if "i" is the index of
":" in ":{x}", and "j" is the index of "}" in ":{x}",  "j - i == 3" is true.
Also add a test case for SPR-16663.

* pr/1759:
  Nested "enum"s should not be declared static

Closes gh-1759

This commit introduces tests for looking up annotations on parameters
in constructors for nested and inner classes via Spring's
MethodParameter abstraction.

The test for an inner class is currently disabled since it fails on
JDK 8. See JIRA issue for details.
