[rules-users] StackOverflowError when serializing KnowledgeBase
Hello,
After adding a few hundred rules, and with the same code, KnowledgeBase serialization has
started to generate StackOverflowError. I have increased the VM stack size as a
workaround, but I was hoping to implement something more robust.
I specifically need to serialize the KnowledgeBase, and not the session.
I'm using this code:
private void dumpKnowledgeBase(String file, KnowledgeBase kbase) {
try {
FileOutputStream ostream = new FileOutputStream(file);
DroolsObjectOutputStream p = new DroolsObjectOutputStream(ostream);
p.writeObject(kbase);
p.flush();
ostream.close();
}
catch (Exception e) {
System.err.println(e);
e.printStackTrace();
System.err.println("Could not write knowledge base "+file);
}
}
This is due to writeObject recursion? Any ideas?
