java.lang.NoClassDefFoundError : Could not initialize class sun. text.normalizer.NormalizerImpl

Question

我在使用 oracle jdk 1.8.0_221(64 位)运行的 wildfly 13 服务器上遇到以下错误。 NormalizerImpl 是 rt.jar 中的一个类，应该始终可用。所以这不是普通的 ClassNotFound。

或类似的

java.lang.NoClassDefFoundError: Could not initialize class sun.text.normalizer.NormalizerImpl
    at sun.text.normalizer.NormalizerBase.isNormalized(NormalizerBase.java:1671)
    at sun.text.normalizer.NormalizerBase.isNormalized(NormalizerBase.java:1652)
    at java.text.Normalizer.isNormalized(Normalizer.java:177)

我用谷歌搜索了它，但没有找到太多，奇怪的是没有找到任何关于SO的信息;-)

Answer 1

我只是提示found是

(1)

The error happens when the JVM jar file resources.jar can not be opened causing a failure during initialization of class sun.text.normalizer.NormalizerImpl and thus raises a java.lang.NoClassDefFoundError. The problem is most probably an incorrect permission on the JVM directories for the connected user. It can be solved by giving read access to group and others: drwxr-xr-x.

(2) 或者他们重新启动了...
