Java getInputstream() - hängt!

[yigiter]

Hallo zusammen,

ich moechte aus einer Url den Inhalt mit getInoutStream() holen, leider funktioniert das nicht immer, so das nach einiger Zeit die Threads keine Rückmeldung geben.

Code:

URL tUrl = new URL(aUrl);

URLConnection tConnection = tUrl.openConnection();

BufferedReader in = new BufferedReader(new InputStreamReader(tConnection.getInputStream(), CHARSET_UTF_8));

in.close();

Hat einer eine Idee! wie das passieren kann!? Und welcher Workaround notwendig ist.. Java 1.6_04

Da sind ja auch wahnsinnig viele Locks drin... was genau machst du denn da? An dem Stück Code was du gepostet hast wird es eher nicht liegen.
