not critical unless we move to jdk8

some details about the problem with java8:

• aop-logging-0.2.3.jar itself is compiled correctly and could be used with JDK1.6+ (include java8)
• but unit tests start in spring 3.x environment which is not compatible with java8

So, existing library source code could be built with any JDK1.6+ and used in applications based on spring3.x or 4.x. But in order to build the library with java8 the unit test should be skipped.
