我在jboss 4.0.2上有一个旧的应用程序。它使用的JDK是1.6（我认为） 我们升级了一些需要JDK 1.8的罐子。所以现在我们已经为Jboss 4.0.2升级到JAVA_HOME的JDK版本到JDK 1.8
现在，当我部署我的应用程序时，它运行正常，但由于某种原因，我不得不删除tmp /和work /文件夹（编译JSP的地方）。现在，当我运行应用程序时，我得到以下错误：

jsps是用jdk 1.4编译的（我认为）和JDK1.8的java.lang.CharSequence的实现是jdk 1.8中的新功能https://community.jaspersoft.com/jasperreports-library/issues/3498-0
唯一的解决方案是我们将JDK降级到1.7。我可以试试。不确定这是否会起作用或将来会出现问题，但在Jboss 7.X中，有一种方法可以指定可以更改。是否有类似的方法在jboss 4.0.2中做到这一点。
另外，如果我的成绩低于JDK 1.7并且工作正常。甚至是一个解决方案，这个应用程序如何在jdk 1.8上工作。
（目前没有针对jboss 4.0.2上的遗留应用程序进行升级）
