[jira] Created: (AXIS-2587) NumberFormatException for new
UnsignedLong( double )
NumberFormatException for new UnsignedLong( double )
----------------------------------------------------
Key: AXIS-2587
URL: http://issues.apache.org/jira/browse/AXIS-2587
Project: Apache Axis
Issue Type: Bug
Components: Basic Architecture
Affects Versions: current (nightly)
Reporter: Alexis Reigel
The double constructor for the class org.apache.axis.types.UnsignedLong raises a NumberFormatException exception if the argument is a double value.
E.g.
<code>UnsignedLong ulong = new UnsignedLong(1D);</code>
The Problem lies in the constructor itself. The line
<code>new BigInteger(Double.toString(value))</code>
calls the constructor of java.lang.BigInteger which expects a string defined as follows: "The String representation consists of an optional minus sign followed by a sequence of one or more decimal digits". In the case of a double value this fails of course.
I'm not sure about the purpose of this constructor anyway. Why would you want to create a long from a double?

[jira] Commented: (AXIS-2587) NumberFormatException for new
UnsignedLong( double )
Posted by "Henri Yandell (JIRA)" <ax...@ws.apache.org>.

Henri Yandell commented on AXIS-2587:
-------------------------------------
Looking at the history of the file (http://svn.apache.org/viewvc/webservices/axis/trunk/java/src/org/apache/axis/types/UnsignedLong.java) it was originally based on a Double rather than a BigInteger. So that would suggest the (double) constructor is either intentional or unintentional legacy.
It was changed in this revision:
http://svn.apache.org/viewvc/webservices/axis/trunk/java/src/org/apache/axis/types/UnsignedLong.java?r1=257456&r2=259888
as a part of https://issues.apache.org/jira/browse/AXIS-1344.
