Remove all blank lines from test code so that test methods are
visually grouped together. This generally helps to make the test
classes easer to scan, however, the "given" / "when" / "then"
blocks used by some tests are now not as easy to discern.
Issue gh-8945
Update all ternary expressions so that the condition is always in
parentheses and "not equals" is used in the test. This helps to bring
consistency across the codebase which makes ternary expression easier
to scan.
For example: `a = (a != null) ? a : b`
Issue gh-8945
Reduce method visibility for package private classes when possible.
In the case of abstract classes that will eventually be made public,
the class has been made public and a package-private constructor has
been added.
Issue gh-8945
Ensure that `equals` `hashCode` and `toString` methods always appear in
the same order. This aligns with the style used in Spring Framework.
Issue gh-8945
Use regular expression search/replace to ensure all single-arg
lambdas have parenthesis. This aligns with the style used in Spring
Boot and ensure that single-arg and multi-arg lambdas are consistent.
Issue gh-8945
Add an additional lines after the copyright header and before the
`package` declaration. This aligns with the style used by Spring
Framework.
Issue gh-8945
Replace static imports with class referenced methods. With the exception
of a few well known static imports, checkstyle restricts the static
imports that a class can use. For example, `asList(...)` would be
replaced with `Arrays.asList(...)`.
Issue gh-8945
Migrate Mockito imports to use the BDD variant. This aligns better with
the "given" / "when" / "then" style used in most tests since the "given"
block now uses Mockito `given(...)` calls.
The commit also updates a few tests that were accidentally using
Power Mockito when regular Mockito could be used.
Issue gh-8945
Refactor `HeadersBeanDefinitionParser` and `AclImpl` to reduce the
number of nested if statements. A few extracted methods are now used
to hopefully improve readability.
Issue gh-8945
Move all inner-types so that they are consistently the last item
defined. This aligns with the style used by Spring Framework and
the consistency generally makes it easier to scan the source.
Issue gh-8945
Replace code of the form `a = b =c` with distinct statements. Although
this results in more lines of code, they are usually easier to
understand.
Issue gh-8945
Apply an Eclipse cleanup rules to ensure that fields are always accessed
using `this.`. This aligns with the style used by Spring Framework and
helps users quickly see the difference between a local and member
variable.
Issue gh-8945
Update classes that have private constructors so that they are also
declared final. In a few cases, inner-classes used private constructors
but were subclassed. These have now been changed to have package-private
constructors.
Issue gh-8945
Use '^\s+//\ \~\ .*$' and '^\s+//\ ============+$' regular expression
searches to remove superfluous comments.
Prior to this commit, many classes would have comments to indicate
blocks of code (such as constructors/methods/instance fields). These
added a lot of noise and weren't all that helpful, especially given
the outline views available in most modern IDEs.
Issue gh-8945
Getting StackOverflowError when invoke AclImpl.hashCode because of
cross-references between AclImpl and AccessControlEntryImpl
Remove from AccessControlEntryImpl.hashCode method invocation of
acl.hashCode
fixes gh-5401
