Server and client get out of sync after multimap get with metadata operation ---------------------------------------------------------------------------- Key: ISPN-11630 URL: https://issues.redhat.com/browse/ISPN-11630 Project: Infinispan Issue Type: Bug Components: Hot Rod, Multimap Affects Versions: 11.0.0.Dev04, 10.1.6.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Labels: testsuite_stability Fix For: 11.0.0.CR1, 10.1.8.Final The Hot Rod server includes metadata information with the {{GET_MULTIMAP_WITH_METADATA_REQUEST}} response even if the status is {{KEY_DOES_NOT_EXIST_STATUS}}, but the client does not expect any other information after the header, so it tries to read the metadata information as the start of a new response and fails: {noformat} 08:50:15,468 TRACE (testng-Test:[]) [Codec] [] Wrote header for messageId=47333 to PooledUnsafeDirectByteBuf(ridx: 0, widx: 14, cap: 19).
