    Description

      The JPA classes use java.lang.instrument.ClassFileTransformer for class transformation, however this style of transformer incurs an extra whole-byte-array copy when loading memory-mapped classes or using other resource loaders which operate on byte buffers.

      After the Modules 1.8.0.Final upgrade, switch to using org.jboss.modules.ClassTransformer instead.

          Component Upgrade - A task tracking an update to a bundled component or revision of component upstream of the project. WFCORE-3684 Upgrade JBoss Modules to 1.8.0.Final

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.

          Enhancement - An enhancement to or refactoring of existing functionality that is not configurable by an end user (typically a change made by an internal team that affects users) WFCORE-3685 Use org.jboss.modules.ClassTransformer for transformation DUPs

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
