Codacy warns us that there are several references to Boolean
constructors in the tests. Direct usage of the Boolean constructor is
discouraged and even deprecated in Java 9 [1]. Boolean constructor use
can easily be replaced with the constant instances.
This commit contains the following changes:
- replace references to Boolean constructors with boolean constants in
JSP tag tests
- update the copyright year where necessary
- BooleanComparatorTests is intentionally left unchanged as it should
also work with the non-constant instances correctly

Codacy warns about an Error Prone [1] use of the double constructor of
BigDecimal in tests. The reason given is that it is a source of
precision loss if the number does not have an exact double
representation. The recommendation is to use the String constructor of
BigDecimal instead as it does not require using a lossy argument.
This commit contains the following changes:
- replace usage of the double constructor of BigDecimal with the
String constructor of BigDecimal in JdbcTemplateQueryTests
- update the copyright year

ScriptUtils contains two calls to String#toCharArray for the sole
purpose to iterating over all chars in a String. Not only is this
unnecessary and can be replaced with String#charAt it also causes
additional allocator and heap pressure because String#toCharArray
rather than returning the backing array (which is gone in Java 9)
creates a copy.
This commit contains the following changes:
- remove String#toCharArray from ScriptUtils and replace with
String#charAt

Prior to this commit, the `ResourceRegionHttpMessageConverter` would
rely on the default implementation of `getDefaultContentType` to guess
the default Content-Type of the resource region to be written to the
HTTP response. That implementation fetches the first media type
provided in the HTTP request "Accept" header.
This behavior is not correct when converting resources and this commits
aligns this converter with the `ResourceHttpMessageConverter` which uses
JAF to guess the correct Content-Type of the given resource, or just
returns "application/octet-stream" as a default value.
