RE: [aspectj-users] Plans for the next release of AspectJ...
|
JDK 1.5 will allow JVMs to use some very agressive optimisation techniques, largely thanks to changes to the Java Memory Model (JMM). One example: if the JVM can prove to itself that a synchronized block is not required, the compiler could remove the synchronization. Another example: current JVMs already allow code to migrate from outside a sync block to inside that block.
If aspectj was trying to track sync blocks, how well does/would aspectj cope with such optimizations?

Can you give a couple of small example programs showing how you'd use this? At least one with TYPE_PAT and one with FIELD_PAT?
One issue is that I'm not sure I can see how field_pat would work stably.
