[eclipselink-dev] Fix for bug# 316991: Attribute.getJavaMember() returns

["Michael O'Brien" <michael.obrien@xxxxxxxxxx>]

Everyone,
   The following patch for bug# 316991 is available for review.
   The issue is that any call to Attribute.getJavaMember() for 
Embeddables returns null instead of a Field or Method for @Embeddable 
types optionally used as @EmbeddedId.
   The fix for DI95 getJavaMethod() call on attribute of @Embeddable 
requires handling for a null getMethod by doing a reflective call on the 
managedType using the method name.  We need the same reflective code 
from ManagedTypeImpl.initialize() that gets the Member using the method 
or attribute name when the getMethod is missing.
