Re: Clojure in OSGi and *use-context-classloader*
Hi there,
Thanks for your post. I had the same problem and your solution is what I
need.
To answer your question, USE_CONTEXT_CLASSLOADER still returns true in the
following method (which is also in RT.java) because it is being bound to
true when making a DynamicClassLoader:
static public ClassLoader makeClassLoader(){
return (ClassLoader) AccessController.doPrivileged(new PrivilegedAction(){
public Object run(){
try{
Var.pushThreadBindings(RT.map(USE_CONTEXT_CLASSLOADER, RT.T));
// getRootClassLoader();
return new DynamicClassLoader(baseLoader());
}
finally{
Var.popThreadBindings();
}
}
});
}
So what I did was change the binding to RT.map(USE_CONTEXT_CLASSLOADER,
RT.F), and that works.

Could it be that you run multiple threads and the var is true in a thread and false in the other? Just a guess.

Clojure in OSGi and *use-context-classloader*
I am using clojure in apache karaf which has Thread context class loader
set to karaf jars.
I changed use-context-classloader to false in RT.java:
final static public Var USE_CONTEXT_CLASSLOADER =
Var.intern(CLOJURE_NS, Symbol.intern("*use-context-classloader*"),
F).setDynamic();
For some reason booleanCast(USE_CONTEXT_CLASSLOADER.deref()) doesn't always
return false and RT still managed to create DynamicClassloader with thread
context
classloader as parent. Of course, it wasn't able to find any clojure
classes.
To make it work I commented out this line in baseLoader() method.
else if (booleanCast(USE_CONTEXT_CLASSLOADER.deref())) {
return Thread.currentThread().getContextClassLoader();
}
Why booleanCast(USE_CONTEXT_CLASSLOADER.deref()) doesn't always return
false ?
