Hi Rick,
Best wishes for the New Year.
Dalibor and I will be at FOSDEM '17, Brussels 4 & 5 February. Let us
know if you will be there, hopefully we can meet up !
Hi Rory and Dalibor,
I won't be attending FOSDEM next month, so I'm afraid I won't see you.
I have taken build 151 for a test-drive. I'd hoped that it would fix the
problems which surfaced in build 148.
Unfortunately, build 151 does not fix the following problem which
surfaced in build 148: the failure of our test harness to find the
derbyall suite. The problem seems to be that the Java 9 class loader no
longer finds resources which the Java 8 class loader can locate. The
following sample program demonstrates this problem. Compile this program
with jdk 8 and put the derby jars on your classpath. This is the output
when you run the program on jdk 8...
input stream =
sun.net.www.protocol.jar.JarURLConnection$JarURLInputStream@3f99bd52
...and this is the output when you run the program on jdk 9...
input stream = null
Here is the program:
public class Derby6856_MissingResource
{
public static void main(String... args) throws Exception
{
String resourceName =
"/org/apache/derbyTesting/functionTests/suites/derbyall.properties";
Class dummyClass = (new Object()).getClass();
Object is = dummyClass.getResourceAsStream(resourceName);
System.out.println("input stream = " + is);
}
}
It appears that resource resolution has changed significantly in the
recent builds of JDK 9. I expect that this change will be an unwelcome
surprise to many users. I have a couple questions:
1) Is this new behavior a bug?
2) Is there a recommended workaround?
Thanks,
-Rick

o Phases in which increasing levels of scrutiny are applied
to incoming changes.
o In phase 1, only P1-P3 bugs can be fixed. In phase 2 only
showstopper bugs can be fixed.
