RE: AspectWerkzPreProcessor throwing exception on null class name

Alex,

Yes, NetBeans is an IDE, open source, supported primarily by Sun
(http://www.netbeans.org).

Here is what we are doing with NetBeans as it relates to AspectWerkz:

As part of an overall layered architecture, we are developing a business
layer using NetBeans as our IDE. Within NetBeans, we develop, compile, and
run various Java classes and related test cases. To make the development
cycle less painful, we use the online weaving functionality of AspectWerkz
to apply our aspects whenever a test case is executed (so that we don't have
an extra post-compiler step to modify the class file). We're using the
prepared bootclasspath approach. NetBeans lets us define the execution
command line, so that we can easily apply the -X argument and the additional
classpath jars.

All this works great except the numerous exceptions thrown as I mentioned.

Hope that helps clarify. I'll be happy to contribute a set of instructions
for setting up NetBeans to do the online weaving if you think other users
would find that helpful.

Thanks for make the change, that will make our integration much more smooth.

Good point Steve
I'll had that in 0.10.RC3. Hope to ship it next week.
(Note: defining a null named class is a deprecated method in
java.lang.ClassLoader - but I understand you cannot change this)

BTW: NetBeans is an IDE right ? Could you give some more details on what you
do with "integrating NetBeans and AW" ? Have an AW IDE extension or use AW
to add Aspects in the IDE for dev. purpose etc ?

Alex
