Hi,

doing a bit of digging it appears a similar improvement - along with a lot of other things - was suggested and filed a few years back:

https://bugs.openjdk.java.net/browse/JDK-8029019

Peter, this enhancement is currently assigned to you, but I guess you're not actively working on it. Any objection if I create a subtask to deal with the observed performance issue in AnnotationInvocationHandler.invoke - or do you want to revisit the enhancement in full?

Thanks!

Hi,

Thank you for the quick response. I've signed the OCA already according to the contribution guidelines - I just wasn't sure where to put such a trivial enhancement. In a 10 minute profile I had around 600MB of allocations for cloning the types, so roughly 1MB/s. If you need the screenshot, I can post it tomorrow. Anything you need from me in order to proceed? Cheers, Christoph
