Subject Re: svn commit: r1236823 - in /aries/trunk/proxy/proxy-impl: ./ src/main/java/org/apache/aries/proxy/impl/common/ src/main/java/org/apache/aries/proxy/impl/gen/ src/main/java/org/apache/aries/proxy/impl/interfaces/ src/main/java/org/apache/aries/prox

As I mentioned earlier, ASM4 has forgotten to add one method isHasSVUID()
although it was javadoced . As I have not looked at the implementation of
computeSVUID and you said it will be computed every time, I do agree your
suggestion is better for the time being. We will be able to change this
class when ASM4 fixes the problem or enhances their class. Will commit the
change soon.

Thanks
Emily
