DMR operation register-proto-schemas fails with NPE if the proto file has syntax errors --------------------------------------------------------------------------------------- Key: ISPN-7405 URL: https://issues.jboss.org/browse/ISPN-7405 Project: Infinispan Issue Type: Bug Components: Remote Querying, Server Affects Versions: 9.0.0.Beta2 Reporter: Adrian Nistor Assignee: Dan Berindei Priority: Blocker Fix For: 9.0.0.CR2 Attachments: error.log Start an infinispan server and run the following CLI command: ./bin/ispn-cli.sh -c '/subsystem=datagrid-infinispan/cache-container=local:register-proto-schemas(file-names=[myFileWithSyntaxErrors.proto], file-contents=[kaboom])' since the file has syntax errors it should still be placed in the ___protobuf_metadata cache and a myFileWithSyntaxErrors.proto.errors key should also be created. No exception should be thrown. Currently no key is written in cache and the NPE from the attached log happens. When registering a proper file without syntax errors this works correctly. The problem disappears if I disable global state persistence, so the cachestore seems to play a role in this.
