Hi,

I'm using annotation

{code:java} @Pool(value = PoolDefaults.POOL_IMPLEMENTATION_STRICTMAX, maxSize = 1, timeout = 10000) {code}

to implelement a singleton bean. It is working fine - concurrent calls to bean are blocked. But if exception occurs in bean method, the instance is discarded and new created instances seems to ignore max pool size setting. I can observer parallel execution of bean methods.

It can be important that this singleton bean is called from other bean that is called with AsyncUtils.mixinAsync, so:

Bean A calls bean B with AsyncUtils.mixinAsync

Bean B call singleton bean C

All components are stateless

It is critical part of my solution, do you have some advice how to workaround this error?
