Cannot run yoko without permission to create a security manager
---------------------------------------------------------------
Key: YOKO-302
URL: https://issues.apache.org/jira/browse/YOKO-302
Project: Yoko - CORBA Server
Issue Type: Bug
Components: orb core
Affects Versions: v1.0-incubating-M2
Reporter: David Jencks
Attachments: YOKO-302.patch
I've run into a situation where I'm trying to use yoko in an environment where
it doesn't have permission to create a security manager. UtilImpl and
UtilLoader have the same code with a static field
// Note: this field must be declared before the static intializer that
calls Util.loadClass
// since that method will call loadClass0 which uses this field... if it is
below the static
// initializer the _secman field will be null
private static final SecMan _secman = new SecMan();
static class SecMan extends java.rmi.RMISecurityManager {
public Class[] getClassContext() {
return super.getClassContext();
}
}
which is used in an attempt to load a class:
ClassLoader stackLoader = null;
Class[] stack = _secman.getClassContext();
for (int i = 1; i < stack.length; i++) {
stackLoader = stack[i].getClassLoader();
if (stackLoader != null)
break;
}
if (stackLoader != null) {
try {
result = stackLoader.loadClass(name);
} catch (ClassNotFoundException ex) {
// skip //
}
if (result != null) {
return result;
}
}
obviously, in an environment where we don't have permission to create a
security manager this will fail.
Patching the code to continue if it can't create the security manager works
fine for the situation I've encountered. Are there any other bad effects?
