[12] RFR JDK-8212735:Compilation issue with javax.swing.InputVerifier example in javadoc section

[Prasanta Sadhukhan]

Hi All,

In 
https://download.java.net/java/early_access/jdk12/docs/api/java.desktop/javax/swing/InputVerifier.htmljavadoc, 
the example given does not compile as the "field" variable is not declared.
Following fix ensures proper variable is used. Checked the example works 
after this.
