Oh yeah, I've got obscure errors after hot reloading hundreds of times.
Most of them were JNDI-related, by the way ;)

That's it - JSPs came to my mind even before the idea of generating
annotated classes. Needless to say I did some testing...

The results were, errr, a bit disappointing.
TomEE 7.0.0-M3
==============
tx = null
bm = org.apache.webbeans.container.InjectableBeanManager@b4ecb2
@PostConstruct: invoked
WildFly 10.0.0
==============
tx = null
bm = null
@PostConstruct: not invoked
GlassFish/Payara 4.1.1
======================
bm = (had to remove BeanManager since JSP didn't compile)
tx = null
@PostConstruct: not invoked
Is it another blind-spot in the spec? or is it a bug? or am I doing it
totally wrong?
