Richard N. Hillegas commented on DERBY-7126:
--------------------------------------------
As feared, the Derby tests now fail spectacularly against JDK 18. When I try to
run a single JUnit test...
{noformat}
java junit.textui.TestRunner
org.apache.derbyTesting.functionTests.tests.lang.DistinctTest
{noformat}
...I get the following error
{noformat}
Could not create and run test suite: java.lang.UnsupportedOperationException:
The Security Manager is deprecated and will be removed in a future release
{noformat}
In addition, under JDK 18 Derby now fails to install a default SecurityManager
when the user boots the server. This causes the server to silently fail to boot.
{noformat}
java -jar /Users/rhillegas/derby/mainline/trunk/jars/sane/derbyrun.jar server
start
{noformat}
According to the email thread mentioned above, to install a SecurityManager,
you need to specify the following system property:
{noformat}
-Djava.security.manager=allow
{noformat}
I am inclined to make that change to the NetworkServer so that we can continue
to limp along until the Open JDK folks figure out their replacement for the
SecurityManager. We may want to update the Derby Security Guide to say that
this property is required from JDK 18 onward, if you want to run with a
SecurityManager.
