SRL tool behaves differently when called more than once with same information
Tested out of the online GUI, on a project called ow2_joram in the hosted PKM (a clone of OW2 joram project).
Call follows (note: each call lasts... about 5 minutes)
The 1st call seems to return something valid, and subsequent calls null (according to the tool execution results). See the last lines: also note that it does not happen with all files and annotations, only some of them.
