[jboss-jira] [JBoss JIRA] (DROOLS-5681) ByteArrayResource byte attribute read/write twice

Sylvain Lemoine created DROOLS-5681: --------------------------------------- Summary: ByteArrayResource byte attribute read/write twice Key: DROOLS-5681 URL: https://issues.redhat.com/browse/DROOLS-5681 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.43.1.Final Reporter: Sylvain Lemoine Assignee: Mario Fusco When using Java standard serialization mechanism, we can see that ByteArrayResource is now written twice in ByteArrayResource {code:java} @Override public void writeExternal(ObjectOutput out) throws IOException { super.writeExternal( out ); out.writeObject( bytes ); out.writeObject(this.encoding); }{code} And super class writeExternal: {code:java} public void writeExternal(ObjectOutput out) throws IOException { //... out.writeObject( bytes ); }{code} It works as it also read twice in ByteArrayResource#readExternal and ByteArrayResource#writeExternal. Anyway, moving the bytes attributes from child class to super class broke our project serialization as we rely on java serialization for our KieBase resources. Seems ok as we'll address it by some tweaking on serial uid, but fixing this issue (read/write once instead of twice) will also break sdeserialization for project which rely on it from 7.34.0.Final.   Don't know if it's okay to fix it in the next version. I can make a PR for this case.     -- This message was sent by Atlassian Jira (v7.13.8#713008)
