如何解决将Keycloak升级到11.0.0
要在所有节点上合并指标，插件将这些值存储在Infinispan缓存中。通过将Keycloak升级到版本11，该插件仅适用于（Infinispan）节点。一旦第二个节点运行，Infinispan似乎在将数据保存到缓存（合并或放置）时找不到缓存类。但是，阅读权限确实有效。
该插件自Keycloak 6开始运行，没有任何问题，只有库已更新以匹配Keycloak版本。
一些观察结果：
- 仅通过一个节点访问infinispan缓存就可以正常工作
- 第二个节点联机后，缓存将正确同步
- 在线读取具有两个节点的缓存确实可行
- 在线访问两个节点的缓存会产生CNF异常
- 关闭节点并写入正在运行的节点上的缓存确实可以再次工作
- 重新启动第二个节点，缓存将再次正确同步，但是写入缓存再次崩溃

MetricsCache确实在初始化时访问CacheManager：
cacheManager = (EmbeddedCacheManager) new InitialContext().lookup("java:jboss/infinispan/container/keycloak");
随后将直接创建缓存：
if (!cacheManager.cacheExists(cacheName)) {
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.clustering().cacheMode(CacheMode.disT_ASYNC);
cacheManager.defineConfiguration(cacheName,cb.build());
}
cache = cacheManager.getCache(cacheName,true);
读取缓存：
Long value = cache.get(key);
写入缓存：
cache.merge(key,value,Long::sum)
插件module.xml：
<?xml version="1.0" encoding="UTF-8"?>

直到今天，我仍未找到上述例外的解决方案，欢迎任何解决我的问题的提示和想法。
谢谢！
