WELD-862 and Seam Cron
by Peter Royle
Hi,
I'm aiming to make a release of Seam Cron available within the next two weeks. Currently there is an outstanding issue (https://issues.jboss.org/browse/WELD-862) which prevents Cron from running properly with Weld. I have been able to carry on developing Cron by testing it against OpenWebBeans, but obviously if we are to release a Seam module it should work against Weld.
It would be nice if WELD-862 could be fixed as soon a possible so that all future versions will work well with Cron.
But more importantly I also probably need to do something special in Cron so that it will work with the version of Weld already deployed in JBoss AS and Glassfish, which will contain the bug. The workaround mentioned in the bug report is to deep copy the InvocationContext. I attempted to do this by serialising and unserialising the InvocationContext but couldn't due to UnserializableExceptions. Does anyone have any advice for me about how I might be able to work around this bug to support existing versions of Weld?
Cheers,
Pete R

Re: [weld-dev] [cdi-dev] microbenchmark for CDI performance
by Jozef Hartinger
Btw I've run your benchmark locally and observed the following results:
OWB 1.2.6: 9827ms
Weld 2.2.5.Final: 20ms
;-)
I did however tweak the test a bit so that Weld's optimizations can be
leveraged[1]. I admit that in certain situations (like your test without
my change) Weld performs worse than it should and this is a good input
for us.
As for the NPE you observed not sure what is going on there. Perhaps
WeldContextControl implementation in DeltaSpike is not really thread safe?
