identityHashCode(this) returns randomly negative values causing exception.

[roizpi]

Reported Class name: GroovyContentHandlerFactory.java

The failure scenario is as follows:

Being the generated name: SmooksVisitor_-194858501_3, its returned hash value is sometimes negative (others not), throwing the following exception:

org.milyn.cdr.SmooksConfigurationException: Error constructing class from Groovy script

This seems to be related with the environment running over Linux.

The code causing the problem is:
private synchronized String createClassName() {
StringBuilder className = new StringBuilder();

className.append("SmooksVisitor_");
// This line gives random positive or negative values. At least over Linux.
className.append(System.identityHashCode(this));
className.append("_");
className.append(classGenCount++);

return className.toString();
}

This may help fixing the issue.
