Scott Marlow commented on WFLY-10025:
-------------------------------------

Looks like we are clear to proceed on this, as Modules 1.8.5.Final (or newer) appears to be in wildfly-core now.

> 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.
