[infinispan-issues] [JBoss JIRA] (ISPN-11250) Unexpected functionality added by Java8 default interface methods

Wolf-Dieter Fink created ISPN-11250: --------------------------------------- Summary: Unexpected functionality added by Java8 default interface methods Key: ISPN-11250 URL: https://issues.redhat.com/browse/ISPN-11250 Project: Infinispan Issue Type: Bug Reporter: Wolf-Dieter Fink With Java8 there are interfaces which implement default methods. Those defaults are available if not overridden, but the function behind might not be correct because the method was not meant to be implemented. There are issues with the transaction and locking because of the remote invocation, so the conditional operation will not work consistent. Such methods need to be checked and throw a UnsupportedOperation. This appears for the compute(...) methods compute(key, BiFunct) -> default to java.util.concurrent.ConcurrentMap interface compute() methods with expiration will throw an UnsupportedOperationException as expected. -- This message was sent by Atlassian Jira (v7.13.8#713008)
