Michael Jumper commented on GUACAMOLE-425:
------------------------------------------
It looks like the issue here is indeed Glassfish. Scrounging through the
Glassfish code, I found [the code which produces that
{{RuntimeException}}|http://grepcode.com/file/repo1.maven.org/maven2/org.glassfish.web/war-util/3.0/org/glassfish/web/loader/WebappClassLoader.java#944]:
{code:java}
...
try {
...
} catch (Throwable t) {
String msg = rb.getString(
"webappClassLoader.unableToLoadClass");
msg = MessageFormat.format(msg, name, t.toString());
throw new RuntimeException(msg, t);
}
...
{code}
Glassfish' internal class loader implementation has a blanket catch-all for any
{{Throwable}} that isn't handled by the class loader itself, in this case a
{{NoClassDefFoundError}}, which rethrows everything as a {{RuntimeException}}.
This will mask all but a few exception classes, breaking any web application
which relies on actually catching {{NoClassDefFoundError}}, such as Guacamole.
If newer versions of Glassfish suffer from the same problem, I guess we'll have
to broaden the exception handling within the WebSocket support detection
modules to defend against such things. In the meantime, using a different
servlet container like Tomcat or Jetty should work great.
