Java Source File Sequencer Problems When Sequencing Interfaces, Typed Collections, And Nested Types

I found these problems with the java source sequencer:

• Collection types are missing. So Collection<Integer> is saved as Collection
• Variables declared in the same statement are missing. For example, only variable j is persisted in this statement: int i, j;
• The .* in wildcard imports is not saved. So import a.b.*; is saved as import.a.b
• The array indicator is not saved in the type. So Object[] is saved as Object
• AbstractMetadata.SYNCRHONIZED is misspelled.
• Nested inner types (classes, interfaces, enums) are not saved.
• enum parameters are missing. So A("a"), B("b") is saved as A, B
• AbstractJavaMetadata.createTypeMetadata does not process modifiers for interfaces. So a public interface will end up being package scoped.
• AbstractJavaMetadata.createTypeMetadata does not process methods for interfaces.
• comments are lost
• method body is missing

Some of the above may require CND changes (like adding comments, method body, and nested types).
