Kathey Marsden updated DERBY-700:
---------------------------------

    Affects Version/s:     (was: 10.4.1.3)
                           (was: 10.3.1.4)
                           (was: 10.2.2.0)
                           (was: 10.1.3.1)
                           (was: 10.1.2.1)
                           (was: 10.2.1.6)
                           (was: 10.1.1.0)
                           (was: 10.0.2.1)
                           (was: 10.0.2.0)
                       10.6.0.0
                       10.5.3.1
                       10.4.2.1
                       10.3.3.1
                       10.2.2.1
                       10.1.3.3
        Fix Version/s: 10.6.0.0
                       10.5.3.1
                       10.4.2.1
                       10.3.3.1

Adjusting fix version. Fix only works with JDK 1.6 which I think is first supported with 10.3,
so even though the Derby part of the fix went back to 10.1, it will only be effective there
if the older jvms get fixed.    I will put a request in for the IBM jvm to have the jvm fix
backported to at least 1.5.

> Derby does not prevent dual boot from two different classloaders on Linux and Mac OS
X.
> To reproduce run the  program DualBootRepro with no derby jars in your classpath. The
program assumes derby.jar is in 10.1.2.1/derby.jar, you can change the location by changing
the DERBY_LIB_DIR variable.
> On Linux the output is:
> $java -cp . DualBootRepro
> Loading derby from file:10.1.2.1/derby.jar
> 10.1.2.1/derby.jar
> Booted database in loader java.net.URLClassLoader@8ed465
> FAIL: Booted database in 2nd loader java.net.URLClassLoader@dc6a77
> On Windows I get the expected output.
> $ java -cp . DualBootRepro
> Loading derby from file:10.1.2.1/derby.jar
> 10.1.2.1/derby.jar
> Booted database in loader java.net.URLClassLoader@1ac04e8
> PASS: Expected exception for dualboot:Another instance of Derby may have already booted
the database D:\marsden\repro\dualboot\mydb.
