We should no longer rely on MYISAM for the sequence table since this
engine might not always be available. After this change the storage
engine used by the sequence table can be MYISAM or INNODB since the
sequences are allocated using a new connection without being
affected by any other transactions that might be in progress.
To allow users to fall back on the original functionality of using
MYISAM tables for the incrementer, we add a `useNewConnection` flag to
indicate whether or not to use a new connection for the incrementer.
This flag defaults to true.

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
