Subject DO NOT REPLY [Bug 46325] New: ELSupport coerceToNumber() problems
Date Tue, 02 Dec 2008 18:03:29 GMT
https://issues.apache.org/bugzilla/show_bug.cgi?id=46325

           Summary: ELSupport coerceToNumber() problems
           Product: Tomcat 6
           Version: 6.0.18
          Platform: PC
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: regression
          Priority: P2
         Component: Servlet & JSP API
        AssignedTo: dev@tomcat.apache.org
        ReportedBy: bublavas@ecetra.com


1) ELSupport.coerceToNumber() cannot coerce java.math.BigDecimal to
java.lang.Number which is basically a no-op. This is a regression from 6.0.16.

Test-case:

@Test
public void testNumberCoercion() {
        BigDecimal d = new BigDecimal("23");
        try {
                Assert.assertEquals(d, ELSupport.coerceToNumber(d,
Number.class));
        } catch (IllegalArgumentException ex) {
                fail("conversion failed");
        }
}

2) BigDecimal is immutable. The code to convert from BigDecimal to BigDecimal
should therefore return its input, not a copy. (ELSupport.java line 235)
