Je développe une application Java qui utilise une bibliothèque C++. Mon type d'application est un client/serveur RCP (basé sur un plugin eclipse). Le problème est que lorsque j'essaie de connecter plus de 2 clients à mon serveur, ça fronce toujours. Ce qui est étrange, c'est que ce problème se produit, seulement lors de son exécution dans Windows. Sous Linux, cela fonctionne bien.Ma bibliothèque sur les connexions multiples avec mes applications JNI
Je veux également remarquer que, par programmation, les clients sont représentés par des threads C++. Peut être, ils veulent accéder à la même ressource. Si je laisse l'application en cours d'exécution, il en attente de defroze, il se bloque et génère le journal ci-dessous
