记录类的 JAVA_HOME 问题

Question

即使我的 JAVA_HOME 设置正确，我也会收到以下错误。

C:\workspace-sts-2.8.0.RELEASE\JBClient\target>echo %JAVA_HOME%

C:\jdk1.6.0_31

我没有做任何日志记录我只是在我的类路径上有以下依赖项（连同 JRE）

 - concurrent.jar 
 - hornetq-core-client-java5.jar
 - hornetq-jms-client-java5.jar 
 - jboss-aop-client.jar
 - jboss-aspect-jdk50-client.jar jboss-client.jar jboss-common-core.jar

Answer 1

您不是在代码中较早的位置清理/设置系统属性吗？如果java.util.logging.LogManager.readConfiguration 找不到java.home 系统属性，则会抛出此错误。

检查这个answer - 虽然不是完全重复（类不同），但它似乎是同一种问题。
