-------------------------------------------------------------------
I've encountered this issue multiple times in IntelliJ (v10.0.3 CE on OSX
10.6.7 with JDK 10.6.24). Pretty annoying.
Johan's fix resolves it, but I'm a little hesitant to commit the fix because it
doesn't take Camel's {{ClassResolver}} abstracting into account. Sure it calls
{{getCamelContext().getClassResolver().getClass().getClassLoader()}} but this
isn't any different from {{this.getClass().getClassLoader()}}. Perhaps we can
introduce a system property that devs can enable in their IntelliJ
configuration:
{code} //Let us check if we can load this class...
if (System.getProperty("camel.enableIntellijWorkaround") != null) {
ClassLoader classLoader = getClass().getClassLoader();
try {
Class aClass =
classLoader.loadClass("org.apache.camel.core.xml.CamelJMXAgentDefinition");
//Keep going.
} catch (ClassNotFoundException e) {
return false;
}
}
{code}
Of course all of this won't be necessary if someone know the root cause...
