BULL Change Log (jdk 11 or above)

All notable changes to this project will be documented in this file.

[2.1.7-jdk11] 2026.04.01

• Refactors TransformerImpl to use direct field access via reflection utilities instead of string-literal field names, improving maintainability and robustness

[2.1.6-jdk11] 2026.03.31

• Fixes a regression introduced in 2.1.5-jdk11 where field transformers applied to collection elements were incorrectly resolved against the root source object instead of the current element, causing a NullPointerException when a flat field name mapping existed with the same name as the destination field

[2.1.5-jdk11] 2026.03.30

• Fixes an issue that was preventing the transformation of Kotlin classes with default parameter values
• Fixes MissingFieldException when mapping a root-level primitive field into a nested destination object via withFieldMapping (issue #559)
