Fix ReflectionAnalysis plugin to enable AnnotationModel only for Java 5+ #159

Hi @FoggyDawn,
Thanks for your contribution to Tai-e! 😀
Although no instructions were provided on how to reproduce this error, this appears to be an intuitive fix. When the Java version is less than 5, the JRE does not contain the class java.lang.annotation.Annotation, causing
I am inclined to fix this directly with some minor modifications required:
- Use a concise but informative English PR title with proper capitalization, which will later serve as the commit message
- Change
World.get().getOptions().getJavaVersion() > 4toWorld.get().getOptions().getJavaVersion() >= 5, because5more directly indicates that Annotations are available from Java 1.5 onwards (including 1.5). Using4would require an additional mental step to understand the logic.
