[ https://issues.jboss.org/browse/ISPN-6599?page=com.atlassian.jira.plugin.... ] Gustavo Fernandes reopened ISPN-6599: ------------------------------------- The issue appeared again on 9.0.0.Beta1. Does not happen on Alpha4 or 8.2.5.Final. I used the attached reproducer to check it, running in a loop. Steps: * Change in the pom infinispan.version to 9.0.0.Beta1 * Still in the pom, use version 0.4 for <artifactId>infinispan-spark_2.11</artifactId> * Build the uber jar with {code}mvn clean assembly:assembly -DdescriptorId=jar-with-dependencies{code} * Run in a loop {code}java -cp target/node-1.0-SNAPSHOT-jar-with-dependencies.jar com.gustavonalle.infinispan.perf.test.Failover /path/to/server/9.0.0.Beta1 {code} * it will eventually error with {{Exception in thread "main" java.lang.RuntimeException: Invalid cache size! Expected 1000 but it was 999}} meaning entries were lost during topology change -- This message was sent by Atlassian JIRA (v7.2.3#72005)
