When trying to run a launch configuration created in oe11.3 I got
-n requires numeric argument (11996).
To solve this you need to change the oe version in the launch file
<stringAttribute key="abl.client.PROVERSION" value="11.3"/>
to <stringAttribute key="abl.client.PROVERSION" value="11.4"/>
When starting the same with debug PDSOE did detect the real issue
This launch configuration is set to use 11.3 AVM instead of 11.4 AVM.
Hence the OpenEdge version is modified to the current version in the launch configuration.
Reported to tech support as well.
You don't need to edit the file manually. The run configuration dialog has a setting for which AVM you want to use. It is not automatically changed to match the current version.
This problem has been fixed in 11.5 version of PDSOE.
