Hi again,
this is just for curiosity but maybe some T5Guru has a clear explanation:
Do PerThread scoped services needs an interface + implementation ?
I am curios because I noticed these different behaviors:
I setup a registry using t5 - 3.6, define my Module Class with one service
annotated with PerThread Scope. The service depends on other services, and
symbols.
On my Mac, Everything is working fine, running it using mvn exec:java, and
withing eclipse
On my Linux (Ubuntu 12.04) virtual machine I git-pulled the very same project
and run with the same configurations (startup options, dependencies, etc.). In
this case however I got an exception on startup (see below ):
As suggested by the exception, I refactored my code such that ServiceDeployer
has an interface and an implementation. And everything seems to work just fine.
However, I am curios about the different behavior of the same java code on the
two machines.
