Task 'updating upgrade relations for APS packages of application' for a new version of application fails with this error:
system exception, ID 'IDL:omg.org/CORBA/UNKNOWN:1.0'
TAO exception, minor code = 0 (unhandled c++ exception in server side; unspecified errno), completed = MAYBE
In POA 5.5.1 the upgrade declaration syntax has changed, now RQL should be used
<patch match="/application/version >= '1.0'"/>
<patch match="version=ge=1.0" />
Cancel this task, repackage the same version of application with correct syntax and upload the package again.
