Hello,
I am going nuts with an issue I noticed since upgrading to Java 11.
What I am using:
Java 11
Spring Boot 2.1.1 with spring-boot-starter-data-solr (amongst spring-data-jpa
etc)
solr-solrj 7.6.0
What I am doing:
SolrCrudRepository.saveAll(documents)
What I am getting:
2019-01-03 13:47:54.830 ERROR (qtp735937428-22) [ x:documents]
o.a.s.h.RequestHandlerBase java.lang.ClassCastException: class
java.lang.Integer cannot be cast to class java.lang.String (java.lang.Integer
and java.lang.String are in module java.base of loader 'bootstrap')

org.apache.solr.client.solrj.request.JavaBinUpdateRequestCodec$1.readNamedList(JavaBinUpdateRequestCodec.java:130)
What I noticed:
The error seems to be on JavaBinCodec.readSolrInputDocument() where fieldName =
(String)obj;
Initially I thought it was a problem with one of my document so I iterated over
the collection saving each document one by one with
SolrCrudRepository.save(document): in this case I don’t have the
ClassCastException
Am I doing anything wrong? Or is it perhaps a bug?
Any help is very much appreciated!
Kind regards,
Paul
