Cannot remove property from client configuration ------------------------------------------------ Key: WFLY-4789 URL: https://issues.jboss.org/browse/WFLY-4789 Project: WildFly Issue Type: Bug Reporter: Katerina Novotna Assignee: Katerina Novotna The javadoc [1] for javax.ws.rs.core Configurable interface says that: "An existing property can be removed by assigning a null value to the property. " By client.property(some_property, null) this is not possible. ResteasyProviderFactory.property() method only adds the properties, but has no way to remove it if the value of the property is null.
