MapStruct 1.6.1 bug fix released
It is my pleasure to announce the 1.6.1 bug fix release of MapStruct. This release includes 1 enhancement and 8 bug fixes, including some regressions introduced in 1.6.0.
With this release we support the use of the Java 19 LinkedHashSet and LinkedHashMap factory methods.
LinkedHashSet and LinkedHashMap factory method
With this release if your source code is Java 19 or later MapStruct is going to use the new factory methods when creating a Set or Map
On Java 18 or earlier it looks like
Map<AuctionDto, AuctionDto> map = new LinkedHashMap<AuctionDto, AuctionDto>( Math.max( (int) ( auctions.size() / .75f ) + 1, 16 ) ); Set<TargetFoo> set = new LinkedHashSet<TargetFoo>( Math.max( (int) ( foos.size() / .75f ) + 1, 16 ) );
Whereas on Java 19 or later it looks like
Map<AuctionDto, AuctionDto> map = LinkedHashMap.newLinkedHashMap( auctions.size() ); Set<TargetFoo> set = LinkedHashSet.newLinkedHashSet( foos.size() );
Thanks
