Ehcache错误：java.lang.NoClassDefFoundError:net/sf/Ehcache/pool/sizeof/JVM信息

Question

我的组织正在开发一个POC，用于使用terracotta服务器版本4.0.5实现ehcache。使用我的本地机器进行测试时一切正常。

当我们将代码部署到web应用程序时，它可以很好地连接到TSA，但我在尝试创建CacheManager实例时收到以下异常。

我已经验证了所有必需的jar都在类路径中。

ehcache-ee-2.7.5.jar
slf4j-api-1.6.6.jar
slf4j-jdk14-1.7.6.jar
terracotta-toolkit-runtime-ee-4.0.5.jar

它们在我的WEB应用程序WAR的WEB-INF/lib文件夹中。我们在weblogic 10.3.2上运行，JRE为jrmc-3.1.2-1.6.0。

有人知道什么会导致这样的错误吗？感谢您的帮助。

我得到同样的错误，因为Ehcache在尝试查找JRockit JVM参数时得到NullPointerException。尝试使用常规JVM，而不是JRockit。它应该可以解决问题。
