Create a class for each bootstrap phase you want. Create an ordered list of the phase
classes. Iterate over the list. Emit a CDI event for each phase, and have anything that
needs to execute in that phase observe that event and start. Observe the built in
@Initialized ApplicationContext event to kick off your bootstrap class.

Hi all,
I've hit a problem with bootstrapping.
The tests grab the parts of windup through CDI and that initializes them
with defaults.
For example, JavaClassTest#testIterationVariableResolving():
The context initializes at the first line.
When processor.execute() is called, the graph was somehow reused before,
but that's just because of different code in all the execute() methods.
I could simply not set the output dir to WindupProcessorConfig, but the
output is not just where graph is.
I could also check if the graph already has been initialized, but 1)
that would make it nonconfigurable, 2) it would be nonsystemic -
checking in init code if a part of application being initialized was, by
accident, initialized somewhere else.
My suggestion is that we should have kind of bootstrap API for the
graph, similar to WindupProcessor - with a config class, and initialize
it from that.
I don't know how to combine that with CDI, so the tests would have to
use that API instead of CDI.
That's something I have suggested before, and was rejected, perhaps I
didn't explain it clearly back then.
I can't think up any other solution that I would not consider overkill,
like, some CDI providers of the config.
Any suggestions?
