我在Linux Mint 14上安装了Solr 4.9.0和Tomcat 7. Solr不加载默认核心collection1。 Solr似乎正在运行，我可以打开核心管理器。如果我基于此创建其他核心，我会再次收到相同的错误。我已将/ opt / solr /中的默认solr home更改为其他位置，以便能够在版本控制下使用xml文件。
这是我在日志中看到的错误：

将您的Java版本更新为最新版本应解决此问题。 Solr 4.8.0的发布文档说明：
Apache Solr现在需要Java 7或更高版本（建议使用Oracle Java 7或OpenJDK 7，最低版本55;早期版本已知有影响Solr的JVM错误）。
