at java.lang.Thread.run(Thread.java:748)原因及解决方法：
- 检查tomcat启动参数设置，日志有提到一个Xss的配置，在tomcat/bin/Catalina.sh（Linux） | Catalina.bat（Windows）文件中，有可能是配置的启动内存小了
- 因为tomcat启动会去扫描jar包，看错误信息org.bouncycastle.asn1.ASN1EncodableVector是出在这个类，这个类似出现在bcprov*.jar这个包，所以在tomcat的配置文件中配置tomcat启动的时候不扫描这个jar。tomcat/conf/catalina.properties文件，在tomcat.util.scan.DefaultJarScanner.jarsToSkip=里面加上bcprov*.jar过滤
