• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Affects Version/s: framework-0.8.0
• Fix Version/s: scr-1.0.0
• Component/s: Declarative Services (SCR)
• Environment: WinXP, Sun JDK 5.0

Description

activate() calls do not match with deactivate() calls for a delayed component (immediate="false")
and service instances are multiple (although there is no factory)
See the first trace.

If the component is immediate (immediate="false"), the behavior is correct : see the second trace.
The instance is the same singleton for the two clients.
