Solrsearch – java.util.Map $ Entry无法parsing

我有Solr 3.6.2运行和search一个Magento企业网站，它都运行良好，启动时没有错误等。

但是，当试图访问以下pipe理页面：

/solr/admin/stats.jsp
/solr/admin/registry.jsp
/solr/admin/analysis.jsp
/solr/admin/distributiondump.jsp

我收到以下错误：

它总是与java.util.Map $ Entry一样的错误。 pipe理面板中的其他页面似乎工作正常。

这很可能是因为在JSP文件中引用了使用Java 8编译的类文件，Solr本身使用Java 7运行。

解决scheme：或者用Java 7重新编译引用的类，或者用Java 8运行Solr。

你有没有确保JSP包含支持Entry＆java.util.Map的类。

你能发布JSP内容吗？和编译版本？
