public static void redefineClasses(OpenJPAConfiguration conf,

 all the element's methods such that field accesses are intercepted
 in-line. If#canRedefineClasses()returnsfalse,
 this method is a no-op.

canRedefineClasses
public static boolean canRedefineClasses(Log log)
- 
- Returns:
- whether or not this VM has an instrumentation installed that
 permits redefinition of classes. This assumes that all the arguments
 will be modifiable classes according to
 Instrumentation.isModifiableClass(java.lang.Class>), and
 only checks whether or not an instrumentation is available and
 if retransformation is possible.
