Inizia in com.microsoft.java.test.plugin.util.ProjectTestUtils.java, in corrispondenza di parseTestSourcePathString (riga 144), quindi segui getTestSourcePaths e listTestSourcePaths. Riproduci il fallimento del comando delegate e verifica che la richiesta dei percorsi di test per la cartella interessata non generi più la NullPointerException segnalata.
