That line is just a rethrow from a catch block:
final ClassLoader cl = target.getClassPool().getClassLoader();
return AccessController.doPrivileged(new PrivilegedExceptionAction<Class<T>>() //Line 281
{
public Class<T> run() throws Exception
{
return FactoryHelper.toClass(cf, cl); //Line 285
}
});
}
catch(RuntimeException e)
{
throw e;
}
catch (Exception e)
{
throw new RuntimeException(e); //Line 296
}
}
the real work is done here:

I'm not 100% sure, but the marked line would probably be the right place to put it, however that might be a security violation?

Thahks, http://community.jboss.org/people/rebody Huisheng Xu for your replay!! But I`ve included python factory into +*jbpm.default.scriptmanager.xml*+.
I`ve done it as this one - +*<script-language name="python" factory="org.python.jsr223.PyScriptEngineFactory" />*+.
And i checked it debuging code. So, in the class org.jbpm.pvm.internal.script.ScriptManager in the method evaluate(String script, String language)
I`ve got object *ScriptEngine = org.python.jsr223.PyScriptEngine@6ca716*
which have *object interp = org.python.util.PythonInterpreter@17cd18d*
and *object factory = org.python.jsr223.PyScriptEngineFactory(a)f92541.*
*+<script name="invoke script" var="text" lang="python" g="113,18,104,52">
<text>import sys;print "start test!";testvar1 = 2 * 2 + 90;print "testvar1=", testvar1</text>
<transition to="wait" />
</script>+*
By this means that python is visible in jpdl.xml. But when evaluate(ScriptEngine scriptEngine, String script) is run then throw Exception
javax.script.ScriptException: NameError: name 'testvar1' is not defined in <script> at line number 1. For some reason variables can`t be remembered.
May be I try to use wrong factory +*org.python.jsr223.PyScriptEngineFactory???
*+
If somebody hade met with this strangeness.
Thanks alot for replies!!! Andrew

I am getting some failures in tests that have their own classloader when security is enabled, and am unsure where to put the privileged block? Initially I got this error:

Is there any way around this other than adding a properties file for the test containing the permission?
