The constructors of the wrapper classes for primitives (Double,
Integer, Long) have been deprecated since JDK 9 and should no longer be
called. Instead the static factory #valueOf should be used.
Add EPUB output and make all four output formats have links to one another,
to enable discoverability and accessibility (for the folks who need a
particular format to help them read the document).
Due to GenericRecord being checked before SpecificRecordBase,
GenericDatumWriter was used incorrectly for types that extend
SpecificRecordBase.
Resolves#3859
The sample that shows how to provide a custom transaction manager
via a BatchConfigurer has been updated to use the constructor
of `DefaultBatchConfigurer` that takes a DataSource.
Issue #3888
Override SimpleStepBuilder.faultTolerant() in FaultTolerantStepBuilder
to prevent creation of a new FaultTolerantStepBuilder when calling
faultTolerant() on an existing FaultTolerantStepBuilder. Otherwise
configuration, like chunkListeners, are lost.
Issue #3840
Before this commit, the logic that validates if a job
instance is complete or not was based only on the size
of previous parameters, without checking if they are
identifying or not.
This commit introduces a change that uses only
identifying job parameters to identify a job instance
and validate its previous executions.
Issue #1221
Both the PatternMatcher and JdbcParameterUtils use String.toCharArray for
processing. This will create a new char[] which needs to be collected. The
same code has been rewritten to use String.charAt to reduce the overhead.
Additionally unneeded object creation in the PatternMatcher has been removed
as well, to reduce further objects needed to be gc'ed.
StringBuilder by default has a size of 16, however there
are some places that already create larger strings already.
For efficiency and garbage reduction it would be better to have
larger sizes to begin with.
Guarded the logging statements which do concatenation of strings
or calling toString on objects. When a log level isn't enabled
this still would produce garbage that would need to be collected.
Guarded all logging up to info, warn and error can be assumed to be
enabled on a production system.
