“NullPointerException”The number passed in the api is AImage is a null pointer.

[Cici-Musse-Lee]

The file path is org.zkoss.image.AImage.
In our test case, pass inputStream=null into the function whose api is AImage. In this api, a null pointer is introduced when the function init() is called for initialization, and a null pointer exception will be generated.
source code：

public AImage(String name,InputStream is)throws IOException{
    try{
          init (name,Files.readAll(is));
     }finally{
          is.close();
     }
}

test code:

java.lang.string string1 ="{\"key\":null}";
java.io.InputStream inputstream2 = null;
org.zkoss.image.AImage aImage0 = new org.zkoss.image.AImage(string1,inputstream2);
aImage0.isContentDisposition ();

test result

java.lang.NullPointerException:Cannot invoke "java.io.InputStream.close()"because "is"is nullat org.zkoss.image.Almage.<init>(Almage.java:86)
