[jboss-jira] [JBoss JIRA] (WFLY-10025) Use new org.jboss.modules.ClassTransformer interface instead of j.l.i.ClassFileTransformer

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.
