[infinispan-issues] [JBoss JIRA] (ISPN-8815) Server task related caching leaves task unusable until restart

Server task related caching leaves task unusable until restart -------------------------------------------------------------- Key: ISPN-8815 URL: https://issues.jboss.org/browse/ISPN-8815 Project: Infinispan Issue Type: Bug Components: Marshalling, Tasks Affects Versions: 9.2.0.CR2, 9.1.6.Final Reporter: Galder Zamarreño Assignee: Gustavo Fernandes Some caching seems to happen with task that means that if the client uses the wrong marshaller, it doesn't recover until the server is restarted. 1. Take [this code|https://gist.github.com/galderz/ec38a6fbd4b714bffd06a66d4624eb8e] and deploy the tasks associated with it (e.g. full code is [here|https://github.com/infinispan/infinispan-simple-tutorials/tree/8793_...]). E.g. {code} mvn clean package wildfly:deploy {code} 2. The client code works fine as is but instead change execCache to be initialized with data cache, e.g. {code} final RemoteCache<String, String> dataCache = getDataCache(); final RemoteCache<String, String> execCache = getDataCache(); {code} 3. Execute the client code against the server. The server replies with error (this is being addressed in ISPN-8814: {code} mvn clean package exec:exec ... org.infinispan.client.hotrod.exceptions.HotRodClientException: Request for messageId=5 returned server error (status=0x85): java.io.IOException: Unsupported protocol version 100 {code} 4. Change client code so that both {{dataCache}} and {{execCache}} are initialized with {{getExecCache}}, e.g. {code} final RemoteCache<String, String> dataCache = getExecCache(); final RemoteCache<String, String> execCache = getExecCache(); {code} 5. Execute the client again: {code} mvn clean package exec:exec ... org.infinispan.client.hotrod.exceptions.HotRodClientException: Request for messageId=16 returned server error (status=0x85): java.lang.NumberFormatException: For input string: ">5" {code} 6. Restore the client code to be: {code} final RemoteCache<String, String> dataCache = getDataCache(); final RemoteCache<String, String> execCache = getExecCache(); {code} 7. Executing the client again fails: {code} mvn clean package exec:exec ... org.infinispan.client.hotrod.exceptions.HotRodClientException: Request for messageId=16 returned server error (status=0x85): java.lang.NumberFormatException: For input string: ">5" {code} 8. Try redeploying the task: {code} mvn clean package wildfly:deploy {code} 9. Execute client again and same error: {code} mvn clean package exec:exec ... org.infinispan.client.hotrod.exceptions.HotRodClientException: Request for messageId=16 returned server error (status=0x85): java.lang.NumberFormatException: For input string: ">5" {code} 10. Restart the server. 11. Execute the client: {code} mvn clean package exec:exec ... Greeting = Hello developer Sum of values = 45 {code}
