LRUCache has Concurrency problem

## Current behavior Hello, I found the class: [LRUCache](https://github.com/oblac/jodd/blob/master/jodd-core/src/main/java/jodd/cache/LRUCache.java) use `LinkedHashMap` and use read lock for get, but the `LinkedHashMap` `get` method is not thread safe, the element will move...

This implementation contains a sign-extension bug in the finalization step of any bytes left over from dividing the length by 4. https://github.com/xlturing/Simhash4J/blob/master/src/main/java/bee/simhash/main/Murmur3.java#L62 fix please see: https://github.com/apache/commons-codec/blob/master/src/main/java/org/apache/commons/codec/digest/MurmurHash3.java#L397

solon-boot-tomcat添加https支持

1

源码在这里： https://github.com/opensolon/solon/blob/main/__hatch/solon-boot-tomcat/src/main/java/org/noear/solon/boot/tomcat/TomcatServerBase.java 现在不支持HTTPS，Hutool在封装简单的Server门面时，做了实现，可以参考： https://github.com/dromara/hutool/blob/v6-dev/hutool-http/src/main/java/org/dromara/hutool/http/server/engine/tomcat/TomcatEngine.java#L125 懒得提PR了，哈哈，做个参考吧。 Hutool中所有HTTPS的启用都是基于`javax.net.ssl.SSLContext`的，在配置文件中，如果用户传入了这个对象，表示要启用HTTPS，则核心代码为： ```java final Http11NioProtocol protocol = new Http11NioProtocol(); protocol.setSSLEnabled(true); protocol.setSecure(true); protocol.addSslHostConfig(createSSLHostConfig(sslContext)); ``` createSSLHostConfig就是将`SSLContext`构建为`SSLHostConfig`。 tomcat本身提供了一个`org.apache.tomcat.util.net.SSLContext`，因此我弄了一个`JSSESSLContext`将javax的转为tomcat的（PS：tomcat真恶心……），tomcat本身也提供了一个`org.apache.tomcat.util.net.jsse.JSSESSLContext`，不能传`SSLContext`，只能传`KeyManager`之类的，因此我自己写了一个…… 希望对你有用。 > PS：Hutool-6.x在http模块中提供了一个简单的`ServerEngine`接口，用于提供http服务器的门面，类似solon中的`ServerLifecycle`，都是为了简化服务创建和启动差异，也参考了solon的很多实现，在此感谢~~
