PropertyUtils.getProperty(bean,name)出现的问题

at org.apache.commons.beanutils.PropertyUtils.getSimpleProperty(PropertyUtils.java:1175)
at org.apache.commons.beanutils.PropertyUtils.getNestedProperty(PropertyUtils.java:772)
at org.apache.commons.beanutils.PropertyUtils.getProperty(PropertyUtils.java:801)

当属性换用 xxPoint时便不报错。跟踪测试时发现反射得到的属性是 XPoint， 而非xPoint,这是怎么回事呢？

经查证实是commons-beanutils自身bug
