Hi all,
Could I get a couple of review for this small change, please?
And could someone from the JDK side sponsor this change?
Bug: https://jbs.oracle.com/bugs/browse/JDK-8004066
Webrev: http://cr.openjdk.java.net/~kmo/8004066/webrev.00/
The DivModTest introduced in JDK-6282196 [1] checks the contents of
the exception message, but that message isn't specified in JavaDoc and
thus may vary between VM implementations (or even in the same VM).
It looks okay to me, I assume testIntFloorDivMod() could also be changed
to create the ArithmeticException with the no-arg constructor as the
exception message will no longer be tested.
Just a general point, the tests in the jdk repository are not
conformance tests and so it is okay (and normal) for these tests to
exercise highly implementation-specific behavior. They are expected to
be updated and always in sync with the JDK code. Clearly checking
exception messages will a bit fragile, more so in this this case as the
exception messages are coming from the VM.
