[Eclipse Codegen Wizard] comparing NaN with == isn't permitted
--------------------------------------------------------------
Key: AXIS2-2740
URL: https://issues.apache.org/jira/browse/AXIS2-2740
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: Tools
Environment: Java EE 5.0
Reporter: Christophe Denis
Hello all,
The Eclipse Code Generator Plugin Version 1.2 generates some bad code when
making a wsdl to java. In generated types there is a pieces of code like that:
protected double localDoubleNumber ;
// [...]
protected boolean localDoubleNumberTracker = false ;
// [...]
public void setDoubleNumber(double param){
// setting primitive attribute tracker to true
if (param==java.lang.Double.NaN) {
localDoubleNumberTracker = false;
} else {
localDoubleNumberTracker = true;
}
this.localDoubleNumber=param;
}
WRONG: param==java.lang.Double.NaN
isn't allowed because a compare (==) with NaN results everytime with FALSE
(take a look here: http://www.concentric.net/~Ttwang/tech/javafloat.htm)
The result of that bug is, that all elements are tracked, even if they have no
value
RIGHT: java.lang.Double.isNAN(param)
Greetings, Christophe Denis
