我们有一个用1.7编译的老项目，我们想把它的runtime env改为1.8（仍然用1.7编译）。在将runtime env改为1.8之后，我们得到了很多 java.lang.VerifyError 在日志中。对于其中一个：

起初我用 -noverify ，解决了问题。但是我意识到 -noverify 对于生产应用来说不是一个好主意。据我调查，建议升级 javassist 版本。因为在stacktrace中提到了javassist( classpath/ClassName.$javassist_read_YYY()Lcom/classpath/ClassName; @10: ifnonnull )我决定试一试。
我几乎尝试了所有javassist版本，包括3.19（使用jdk8构建），但都不起作用。仍然验证错误。
解决这个问题的办法是什么？或者有解决这个问题的方法吗？
系统信息：jboss 5.1.0.ga和maven 2.2.1
非常感谢你的帮助。
