How many versions of Java do you have? I bet the bin/solr script is using SolrJ (i.e. Java) to communicate with Solr itself (also Java), but for some weird reason they are using incompatible Java versions.
SolrJ uses Java serialization to communicate with Solr, therefore it must use the same Jars and the same Java version in order to succeed at that. Something weird is going on around that area, it seems. Make sure you are using the same Java to start Solr as you are using to run the bin/solr create script, and make sure you are using the same version of Solr, too.
