I'm using Janino to evaluate a script and I don't know how to represent a list of values in the script

I need to evaluate containsAll script, for example: attributeA.containsAll([3,5])
I've tried using [] and Arrays.asList but the compiler either says: "org.codehaus.commons.compiler.CompileException: Line 1, Column 25: Unexpected token "[" in primary" or it says: org.codehaus.commons.compiler.CompileException: Line 1, Column 32: Unknown variable or type "Arrays"
import com.my.project.MyCollection;
import org.codehaus.commons.compiler.CompileException;
import org.codehaus.janino.ExpressionEvaluator;
private static void evalExpression(Map<String, MyCollection> fields)
{
String script= "attributeA.containsAll([3,5])";
try {
ExpressionEvaluator ee = new ExpressionEvaluator();
Class[] parameterTypes = new Class[fields.size()];
String[] parameterNames = new String[fields.size()];
Object[] arguments = new Object[fields.size()];
int i = 0;
for (Map.Entry<String, MyCollection> field : fields.entrySet()) {
String fieldName = field.getKey();
MyCollection fieldValues = field.getValue();
parameterNames[i] = fieldName;
parameterTypes[i] = MyCollection.class;
arguments[i]=fieldValues;
i++;
}
ee.setParameters(parameterNames, parameterTypes);
ee.setExpressionType(Boolean.class);
// And now we "cook" (scan, parse, compile and load) the fabulous expression.
ee.cook(script);
// Eventually we evaluate the expression - and that goes super-fast.
Boolean result = (Boolean) ee.evaluate(arguments);
System.out.println(result);
}
catch (Exception ex){
System.out.println(ex.getMessage());
}
}
I expect the output of false/ true, but instead an org.codehaus.commons.compiler.CompileException is thrown
I added to the script : "import static java.util.Arrays.asList; "
and used the syntax: attributeA.containsAll(asList(3,5))
