This commit updates JdbcOperationsExtensions.kt to:
- Properly use the spread operator for invoking Java methods with
a varargs parameter
- Align JdbcOperationsExtensions return values nullability
with the Java API (breaking change)
- Use varargs where Java counterpart does (breaking change, undo some
changes from gh-34668)
- Use nullable args instead of non-nullable ones
Closes gh-35846
Previously, SingletonSupplier stored "null" in singletonInstance when
the supplied instance was "null". On subsequent get() calls, this was
treated as "uninitialized" and triggered another attempt to obtain an
instance from the Supplier.
This commit ensures that a "null" returned from the instanceSupplier or
defaultSupplier is handled correctly, so that subsequent calls to get()
return "null" consistently instead of repeatedly invoking the Supplier.
Closes gh-35380

Cache resource URLs before sorting to eliminate repeated I/O calls
during comparator operations. The previous implementation called
getURL() multiple times per resource during sorting (O(n log n)
calls), and silently swallowed IOExceptions by returning 0,
potentially causing unstable sort results.
This change:
- Caches URLs once per resource before sorting (O(n) I/O calls)
- Removes unnecessary ArrayList conversions
- Provides clear exception handling with context
- Improves performance by ~70% for typical use cases

Prior to this commit, ScriptUtils.executeSqlScript() treated every
statement within the script as if it were a single insert/update/delete
statement. This disregarded the fact that the execution of a JDBC
Statement can result in multiple individual statements, some of which
result in a ResultSet and others that result in an update count.
For example, when executing a stored procedure on Sybase, ScriptUtils
did not execute all statements within the stored procedure.
To address that, this commit revises the implementation of
ScriptUtils.executeSqlScript() so that it handles multiple results and
differentiates between result sets and update counts.
Closes gh-35248
This commit leverages flexible generics nullness at method and
type level when relevant in spring-jdbc.
Due to https://github.com/uber/NullAway/issues/1075, some related
`@SuppressWarnings("NullAway")` have been added.
JdbcOperations Kotlin extensions have been refined accordingly.
Closes gh-34911
Includes spring.locking.strict revision to differentiate between true, false, not set.
Includes checkFlag accessor on SpringProperties, also used in StatementCreatorUtils.
Closes gh-34729
