need theories about errors seen in the jdk 1.4 test runs

[Rick Hillegas]

Starting on 2011-11-08, the JDK 1.4 test results began to show 2 errors 
which don't appear on other platforms. The errors are NoSuchMethodErrors 
raised by calling a BigDecimal constructor which appears in Java 5 but 
not JDK 1.4. The offending Derby test code was checked in on 2011-03-29 
at subversion revision 1086799 as part of the work on DERBY-2515. I 
would have expected to see this error long before 2011-11-08. Any 
theories about why it popped up only last week?

Thanks,
