jdk8新版本引起的solr起不来

突然solr启不来了，报错如下:

看来是jdk的问题，

查jdk版本是这样的：

1.8.0_333-b02
/usr/java/jdk1.8.0_333-amd64/jre

CentOS Linux release 7.7.1908 (Core)

那么解决方案是换jdk,（以前的都没出过这问题呀）,使用的安装包是：

jdk-8u261-linux-x64.rpm

rpm -qa|grep jdk
rpm -e --nodeps jdk1.8-1.8.0_333-fcs.x86_64

rpm -ivh jdk-8u261-linux-x64.rpm
