velocity 1.7 vs velocity 2.3 : the evaluation of if condition in script is different

script used : 

 
Map<String, Object> variables = new HashMap<>();
variables.put("key1", "value");
 
Context context = velocityEngine.getToolsContext(variables);
 
String inString = "#set($value = \"key value false\")" +
"#if(${key1} == 1 ||\"yes\" )" +
" #set($value = \"{}key value true{}\")" +
"#end\n${value}";
 
inString = velocityEngine.evaluate(context, "tag", inString);
System.out.println(inString);
 
 
Output:
 
older version output : key value true
 
newer version output : key value false
