Why don't breakpoints in around advice work?

Around advice is inlined by the weaver by default, which means that breakpoints set in the declaring aspect are not detected. To disable inlining select Window > Preferences > AspectJ > Compiler. Select the Advanced tab, then check No inline and click OK to apply.
