Bug#605458: [icedtea6-plugin] NULL pointer exception when starting minecraft
I'm experiencing a similar problem, though since it occurs at a different place in the source code, I'm not sure if it's a different bug or just in some slightly different version of NetX where stuff has been moved around. Either way, I fixed the NPE I was having with the following small patch: --- icedtea-web-1.3.1.orig/netx/net/sourceforge/jnlp/runtime/JNLPClassLoader.java +++ icedtea-web-1.3.1/netx/net/sourceforge/jnlp/runtime/JNLPClassLoader.java @@ -1115,7 +1115,7 @@ public class JNLPClassLoader extends URL } // Class from host X should be allowed to connect to host X -if (cs.getLocation().getHost().length() 0) +if ((cs.getLocation() != null) (cs.getLocation().getHost() != null) (cs.getLocation().getHost().length() 0)) result.add(new SocketPermission(cs.getLocation().getHost(), connect, accept)); As you can see, it's a very simple patch with no other side effects, so I don't think it would hurt applying it until upstream can fix the problem for real. -- Fredrik Tolf -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#605458: [icedtea6-plugin] NULL pointer exception when starting minecraft
Package: icedtea6-plugin Version: 6b20-1.9.1-1 Severity: normal --- Please enter the report below this line. --- I tried to start minecraft from http://www.minecraft.net/play.jsp in iceweasel. The first thing I saw was the permission request dialog (pressed yes). After that the loading screen appears and went black afterwards.
