   Java-SDO-M3

 doubleValue() may be inaccurate for Long
 

 Key: TUSCANY-836
 URL: https://issues.apache.org/jira/browse/TUSCANY-836
 Project: Tuscany
  Issue Type: Bug
  Components: Java SDO Implementation
Affects Versions: Java-SCA-Mx
 Environment: Sun JRE 1.5.0_07-b03
Reporter: Yang ZHONG
 Fix For: Java-SDO-M3

 Attachments: Long2BigDecimalTestCase.java


 assertSame(DataObjectUtil.getBigDecimal(new 
 Long(Long.MAX_VALUE)).longValue(), Long.MAX_VALUE);
 complains
 junit.framework.AssertionFailedError: expected 
 same:-9223372036854775808 was not:9223372036854775807
 Potential fix:
 if (value instanceof Long)
 {
   return new BigDecimal(((Long)value).longValue());
 }
 before
 if (value instanceof Number)
 {
   return new BigDecimal(((Number)value).doubleValue());
 }
 Thanks to Marcelo Palladino.
