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
Replace the JUnit Assertions used in `SwitchUserWebFilterTests` with
AssertJ. This test appears to have been missed during the original
AssertJ migration.
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
Add suppressions for existing `InterfaceIsType` violations. Ideally
theses should be classes, but we can't easily change them without
breaking binary back compatibility.
Issue gh-8945
Search and replace using '(?s)/\*\s*\* \(non-Javadoc\).*?\*/' to remove
all "(non-Javadoc)" comments. These comments used to be added
automatically by Eclipse, but are not really necessary.
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
Remove the formatter-on/formatter-off comments from Javadoc examples
so that they don't confuse checkstyle. The comments are not necessary
in the Javadoc since `pre` blocks are not formatted in the same
way as code.
