在使用solrJ访问远程solr时出现该问题，而且相同的代码访问不同的solr，有的可以执行通过，有的会出现如下问题： objc[10523]: Class JavaLaunchHelper is implemented in both  /Library/Java/JavaVirtualMachines/ jdk1.8.0_40.jdk/Contents/Home/bin/java (0x106cb14c0) and  /Library/Java/JavaVirtualMachines/ jdk1.8.0_40.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x107cf64e0). One of the two will be used. Which one is undefined.

解决方案： 这是由于配置的https证书导致的。在配置证书时，会打进去IP地址，该IP地址也就是Solr服务所在的IP，客户端可以使用https的方式来访问该Solr。但是如果证书中的IP配置错误，不是Solr所在服务器的IP，那就客户端访问就可能出现上述的问题。所以请注意，想要用哪些IP来访问该Solr服务，就在证书创建时配置哪些IP。
