I am in the process of upgrading my application from Solr 8.7.0 to Solr 8.11.1. Both the server and solr-solrj-8.11.1.jar have been updated to the same version. Solr servers are on RHEL 7. When I run my client app in JBoss 7 on Windows, all of the SolrJ calls fail with:
java.lang.RuntimeException: Invalid version (expected 2, but 31) or the data in not in 'javabin' format at org.apache.solr.common.util.JavaBinCodec._init(JavaBinCodec.java:213) at org.apache.solr.common.util.JavaBinCodec.initRead(JavaBinCodec.java:202) at org.apache.solr.common.util.JavaBinCodec.unmarshal(JavaBinCodec.java:195) at org.apache.solr.client.solrj.impl.BinaryResponseParser.processResponse(BinaryResponseParser.java:51) at org.apache.solr.client.solrj.impl.HttpSolrClient.executeMethod(HttpSolrClient.java:641) ... 94 more The same application runs just fine when deployed to a RHEL 7 JBoss, it is only on Windows that it fails. The Windows application has been working with no issues until this upgrade. Any ideas? Windows Java version java version "1.8.0_251" Server Java version "1.8.0_311"
