[infinispan-issues] [JBoss JIRA] (ISPN-10862) SpringCache unwrapping NullValue singleton fails with Java Serialization

SpringCache unwrapping NullValue singleton fails with Java Serialization ------------------------------------------------------------------------ Key: ISPN-10862 URL: https://issues.jboss.org/browse/ISPN-10862 Project: Infinispan Issue Type: Bug Components: Spring Integration Affects Versions: 10.0.0.Final Reporter: Ryan Emerson Assignee: Ryan Emerson Priority: Blocker Fix For: 10.0.1.Final, 10.1.0.Final Our spring integration makes use of the {{NullValue.NULL}} singleton when wrapping null values, however the singleton semantics are not respected when Java Serialization is used as this was previously enforced by a {{Externalizer}} implementation. Therefore, the NullValue wrapper is never unwrapped. .SpringCache private ValueWrapper wrap(Object value) { if (value == null) { return null; } if (value == NullValue.NULL) { return NullValue.NULL; } return new SimpleValueWrapper(value); } private <T> T unwrapNull(Object value) { if (value == NullValue.NULL) { return null; } return (T) value; } {code}
