| /** |
| * Test for FELIX-4334 issue. |
| * |
| * Three components: A, B and C |
| * |
| * - A provided with property foo=bar |
| * - B adapts A, B has no filters on A, and B.init() method adds an instance bound required dependency to C. |
| * - C depends on A(foo=bar) |
| * - Now someone modifies the service properties of A: foo=bar2 |
| * - As a result of that, C becomes unavailable and is unbound from B. |
| * - Since B has an instance bound required dependency to C: B should not be destroyed: it should be called in B.stop(), B.remove(C), B.change(A, "foo=bar2)) |
