             Summary: Use new org.jboss.modules.ClassTransformer interface instead of j.l.i.ClassFileTransformer
                 Key: WFLY-10025
                 URL: https://issues.jboss.org/browse/WFLY-10025
             Project: WildFly
          Issue Type: Enhancement
          Components: JPA / Hibernate
            Reporter: David Lloyd
            Assignee: Scott Marlow
            Priority: Minor


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.
