您好，当我启动应用程序时，我会多次收到此错误消息，并且每次使用不同的软件包：
Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.ibex.nestedvm.util.Sort$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.
我使用Mac OsX 10.8上的Eclipse 4.3。
我该如何解决这个问题？
