I tried to use ASTParser to parse text into expressions. 
i.e after calling ASTParser.setKind(K_EXPRESSION);

It works successfully in almost all cases, except for text which is
an array initializer such as:
String text = "{\"red\", \"yellow\"}";
 
The createAST method returns a CompilationUnit node instead of an ArrayInitializer node.

The problem string in the CompilationUnit node is: 
'Syntax error on tokens, delete these tokens'

Note: If the entire Java file is parsed, instead of just the code snippet, 
then the ArrayInitializer node is correctly created. 
So, this problem seems to be only for the ASTParser.setKind(K_EXPRESSION) case.

The code for the test case is as follows:

******************TEST_CASE ****************************************

import org.eclipse.jdt.core.compiler.IProblem;
import org.eclipse.jdt.core.dom.AST;
import org.eclipse.jdt.core.dom.ASTNode;
import org.eclipse.jdt.core.dom.ASTParser;
import org.eclipse.jdt.core.dom.CompilationUnit;

import junit.framework.TestCase;

public class ArrayInitializerTest extends TestCase {

  public void testASTParser() {
		
    String text = "{\"red\", \"yellow\"}";
    ASTParser parser = ASTParser.newParser(AST.JLS3);
    parser.setKind(ASTParser.K_EXPRESSION);
    parser.setSource(text.toCharArray());
    ASTNode node  = parser.createAST(null);
		
    if (node instanceof CompilationUnit) {
      CompilationUnit compilationUnit = (CompilationUnit) node;
      IProblem[] problems = compilationUnit.getProblems();
      StringBuffer buffer = new StringBuffer();
      for (int i=0; i<problems.length; i++) {
        buffer.append("Problem = " + problems[i].getMessage());
      }
			
      fail(buffer.toString());
    }
  }		
}
