Exception while unloading a virtual sensor using local or remote wrappers

[sarni]

I find now that when stopping GSN (ant stop), there is an error if any virtual sensor using local wrapper or either of the remote wrappers.

I can load memoryDataVS.xml and freeDiskSpace-NeedsJDK6.xml and the stop script executes without error.

However if any of:

• diskSpacePlotVS-NeedsJDK6.xml (wrapper="remote-rest">),
• memoryPlotVS.xml (wrapper="local">),
• remote_rest_test.xml (wrapper="remote-rest">) or
• remote_push_test.xml (wrapper="remote">) Are loaded when the stop script is executed, then errors are generated. There is some difference in the errors as can be seen in the attached log file which was recorded while I started and stopped GSN with different VS's loaded.

I guess that errors when stopping are not critical but they may be symptomatic of something more serious.

Did a bit more testing on this issue:

<GSN Release: 1306 Database: MySQL

It seems that the exception is raised when shutting down with a VS loaded that uses one of the remote wrappers to connect to a VS in the same instance (localhost). I am not getting the exception when local wrapper is used.

I have added gsn.log which is a record of several tests warn level and debug.log which is a debug > log of a single test. -- mriahi

Should be solved with v2.0.0
