Everybody,
Here is a small patch provided by KUBOTA Yuji.
http://cr.openjdk.java.net/~dsamersoff/sponsorship/kubota.yuji/JDK-8148104/webrev.01/
The problem:
Running HSDB by jhsdb on CLI i.e. without x11 display, HSDB could
not terminate after throwing HeadlessException.
HSDB starts WorkerThread before making the JFrame. If we run HSDB on
CLI, HSDB throws HeadlessException when makes the JFrame. Thus, the
WorkerThread has never shutdown, then HSDB can not terminate.
Solution:
Create frame before we initialize agent.
While this solution will work in this case I think it would be better to
daemonize the WorkerThread
(hotspot/src/jdk.hotspot.agent/share/classes/sun/jvm/hotspot/utilities/WorkerThread.java)
- that should ensure that the application will be allowed to terminate
even though the worker thread is still running.
