> We are injecting code (like a profiler) using the JVMTI interface.  Normally, we use the JVM options -Xbootclasspath and -agentpath to get our code running, like so:
>    set JAVA_OPTS=-Xmx1024m -Xms1024m -Xbootclasspath/a:C:\\Panorama\\hedzup\\mn\\lib\\awcore\\JIDAcore.jar -agentpath:C:\\Panorama\\hedzup\\mn\\bin\\AwProfile.dll=verbose -Dpanorama.jida.instance=jboss-1
> With JBoss 7, we get a NoClassDefFoundError:
>    Exception in thread "main" java.lang.NoClassDefFoundError: com/altaworks/da/jida/AwMisc
>         at org.jboss.as.server.Main.main(Main.java)
>         . . .
> This is the exact same kind of error that we used to get with OSGI before we modified our code to account for it - in that case we had to inject our package name into the list of packages that OSGI would search the bootclass path for.  As we discussed on the phone today (Rich S), this is likely a similar class loader issue that we're running into with the new JBoss Modules.  I can tell that we are successfully using JVMTI to inject our code.  The problem is that the injected code, as it runs, tries to access classes in our package (com.altaworks.*) which are in our JIDAcore.jar file -- but due to the new class loading scheme, it's unable to find those classes.
> How I reproduce this problem:
>   1. [download and unzip jboss-as-7.0.2.Final.zip]
>   2. SET JAVA_OPTS=... (as above)
>   3. standalone.bat
