David Lloyd created WFLY-10025: ---------------------------------- 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. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
