JRJdk13Compiler shows theses warnings: warning: [removal] Integer(int) in Integer has been deprecated and marked for removal value = new java.lang.Integer(1); //$JR_EXPR_ID=1$ Most probably this deprecated syntax (new java.lang.Integer(int)) is used for initialization of Integer variables defined in the report (built-in variables). Could someone please help me how to change that initialization for Integer.valueOf(int)? Many thanks
