I don't tend to run LTW like that, I use the agent - I think that's what we
recommend. I just ran your code ok:
javac MyClass.java
ajc HelloWorld.java -1.8 -outxml -d out
export CLASSPATH=.:out:$CLASSPATH
java -javaagent:$AJHOME/lib/aspectjweaver.jar MyClass
Hello World from advice
Inside of foo
Are you ok with using the agent? The -outxml line on the ajc call is what
produces the META-INF/aop-ajc.xml file in the out folder, and that is what
the agent will look for to turn on weaving. (That xml file will simply list
the aspects to 'turn on')
cheers,
Andy
