Kelvin Goodson commented on TUSCANY-2009:
-----------------------------------------
I'm surprised that the Ecore equality helper doesn't handle this. If my
understanding is correct then Ecore could check the
eAttribute.getEAttributeType().getInstanceClass().isArray() and then use
Arrays.equals() for all arrays. Maybe there's a fix in a later version of EMF?
This is our only array of primitives type, so we can special case it. We should
check for type Bytes and use java.util.Arrays.equals(arg1,arg2) in our impl of
haveEqualAttribute
> Java SDO's EqualityHelper doesn't compare Bytes values correctly

> Project: Tuscany
> Issue Type: Bug
> Components: Java SDO Implementation
> Affects Versions: Java-SDO-1.0
> Environment: n/a
> Reporter: David T. Adcox
> Fix For: Java-SDO-Next

> Attachments: Test2009.java

>
> Comparison of two Bytes values fails when it should succeed. The test for
> equality passes through the EqualityHelperImpl.equal method. In that method,
> the test is passed to EcoreUtil.haveEqualAttribute(EObject, EObject,
> EAttribute). For a simple type, it defers to java's '==' operator. So, two
> different object arrays are being compared, not for their contents, but
> rather if they are the same object. Attached is a test case which
> demonstrates this issue.
