Java VisualVM bloque la connexion au processus local lancé depuis eclipse

J'essaie de connecter jvisualvm installé avec jdk1.7.0_04 à un processus Java) en cours d'exécution localement. Lorsque je fais cela, jvisualvm affiche une barre de progression en bas à gauche indiquant sa connexion au processus, et puis ne répond plus jamais.

Le processus Java auquel j'essaie de me connecter est toujours correct et fonctionne normalement.

Je peux obtenir un threaddump de visualvm en utilisant jstack, qui montre 1 thread bloqué.

Je ne peux me connecter à aucun processus Java, même un processus trivial qui attend juste l'entrée de l'utilisateur. J'ai également eu le même problème avec jdk1.6.0_32.

- Les mises à jour que j'ai découvertes depuis n'affectent que Java que je lance depuis Eclipse. Il est possible de lancer la commande Eclipse du point de vue du débogage et d'ouvrir les propriétés du processus. Lancement du même processus depuis l'invite de commande (en utilisant la commande que j'ai copiée depuis Eclipse) permet les connexions depuis jvisualvm et jconsole.

Veuillez vérifier la configuration de votre réseau.

J'ai connu le même problème. Cela peut fonctionner lorsque je définis la configuration du réseau avec "No Proxy". Menu principal: tools/options/network/no proxy.

J'ai trouvé ceci sur une liste de diffusion VisualVM: https://Java.net/projects/visualvm/lists/users/archive/2016-06/message/7

Ajouté ceci:

-J-Dorg.netbeans.profiler.separateConsole=true

à mon raccourci jvisualvm.exe et cela fonctionne!

Essayez d'ajouter les arguments VM) suivants à vos "Configurations d'exécution":

-Djava.rmi.server.hostname=localhost

Run configuration

J'avais le même problème et je suis derrière un proxy. La sélection de "No Proxy" ou "Manual proxy settings" résout le problème.

Une chose si simple, et j'ai perdu quelques heures là-dessus ...

Dans mon cas, la solution était d'utiliser jsdk 32 bits.
Pour diagnostiquer, démarrez jvisualvm avec le paramètre --trace ..

mon journal contenait:
Cannot load C:\Program Files\Java\jdk1.7.0_45\jre\bin\server\jvm.dll. %1 is not a valid Win32 application. (193) Falling back to running Java in a separate process; DLL cannot be loaded (64-bit DLL?).

Parfois, Skype se trouve sur des ports étranges ... Cela m'a causé de gros maux de tête à au moins deux reprises, quand il a choisi 8080, et je pensais que mon Tomcat était corrompu. Il s'est avéré (après environ une heure d'être totalement ignorant et sans méfiance), que Skype utilisait ce port ...

Aussi une question: avez-vous démarré votre programme en mode 'Exécuter' ou 'Déboguer' depuis Eclipse?

ppeterka

ajouter l'argument suivant dans l'onglet d'augmentations runConfigurations d'Eclipse

-XX: + StartAttachListener

cela permettra à visualVM de se connecter instantanément et l'échantillon et le profilage fonctionneront.
