Yasuhiro Kawame commented on FELIX-3411:
----------------------------------------
Thank you for your comment.
I am testing exception handling using wrong bundles.
Conditions:
B_N is the bundle start level.
A is an active start level.
R is a requested start level.
Bundle_01:
B_01 = 1
Bundle_02:
B_02 = 3
This BundleActivator#start method throws an exception.
Bundle_03:
B_03 = 5
STEP1. ActiveStartLevel = 1.
(A = 1)
Spec and Implementation:
Bundle_01 is ACTIVE.
STEP2. setStartLevel(3)
(A = 1, R = 3)
Spec and Implementation:
Bundle_02 throws a BundleException.
STEP3. setStartLevel(5)
(A = 3, R = 5)
Spec:
Bundle_03 is ACTIVE.
Implementation:
Bundle_02 throws a BundleException.
Bundle_03 is ACTIVE.
This point is different from Spec.
Best regards.

> Reporter: Yasuhiro Kawame

> I think that the implementation of Changing the Active Start Level is

> OSGi Service Platform Core Specification Release 4, Version 4.3, Figure 8.2

> Spec:
> if (A < R)
> while (A < R) {

> Start All bundles where B = A
> }
> Implementation:
> if (A < R)
> Start All bundles where B <= R
> A = R
> Similarly, if A > R.
