Nested in org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.beans.factory.config.PropertyPlaceholderConfigurer#0': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Method must not be null:java.lang.IllegalArgumentException: Method must not be null

我在部署应用程序时遇到此部署错误。

java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Server VM (build 16.3-b01, mixed mode)

虽然相同的构建在同一服务器jetty 6.1.3中成功部署，但后面的conf。 

java version "1.6.0_17"

使用的弹簧版本是2.5.6.SEC01

如何克服，谷歌搜索没有用？
