我在jre 1.8上使用Java SUSE linux，我在sun/security/tools/keytool/CertAndKeyGen课程上遇到异常。我使用带有maven参数的JDK 1.8构建我的代码
<compilerArgument>-XDignore.symbol.file<compilerArgument>
用于sun / security / tools / keytool / on java 8。构建成功。在jboss上部署后，我收到了java.lang.NoClassDefFoundError的错误。这是完整的堆栈跟踪：
JBWEB000309: type JBWEB000066: Exception report
JBWEB000068: message Handler processing failed; nested exception is java.lang.NoClassDefFoundError: sun/security/tools/keytool/CertAndKeyGen

我从SUSE rt.jar中提取了Jre1.8。我可以看到rt.jar\sun\security\tools\keytool\CertAndKeyGen.class存在于其中。那我为什么得到java.lang.NoClassDefFoundError？
任何帮助或建议？
