Emmanuel Lecharny commented on DIRMINA-1088:
--------------------------------------------
Patch applied to 2.1.0 too.
> OrderedThreadPool implementation should be compatible with Java 10
> ------------------------------------------------------------------
>
> Key: DIRMINA-1088
> URL: https://issues.apache.org/jira/browse/DIRMINA-1088
> Project: MINA
> Issue Type: Bug
> Components: Core
> Reporter: Guus der Kinderen
> Priority: Major
> Attachments: orderedthreadpool.patch
>
>
> {{org.apache.mina.filter.executor.OrderedThreadPoolExecutor}} inherits from
> {{java.util.concurrent.ThreadPoolExecutor}}
> OrderedThreadPoolExecutor, in its constructor, calls these two methods from
> its parent to determine pool sizing:
> {code:java}
> super.setCorePoolSize(corePoolSize);
> super.setMaximumPoolSize(maximumPoolSize);{code}
> This works fine up until Java 8. In Java 10 (possibly 9 - I did not check),
> an additional input validation was added to
> {{ThreadPoolExecutor#setCorePoolSize}}: {{maximumPoolSize < corePoolSize}}
> ThreadPoolExecutor Java 8:
> {code:java}
> public void setCorePoolSize(int corePoolSize) {
> if (corePoolSize < 0)
> throw new IllegalArgumentException();
> public void setMaximumPoolSize(int maximumPoolSize) {
> if (maximumPoolSize <= 0 || maximumPoolSize < corePoolSize)
> throw new IllegalArgumentException();
> {code}
> ThreadPoolExecutor Java 10:
> {code:java}
> public void setCorePoolSize(int corePoolSize) {
> if (corePoolSize < 0 || maximumPoolSize < corePoolSize)
> throw new IllegalArgumentException();
> public void setMaximumPoolSize(int maximumPoolSize) {
> if (maximumPoolSize <= 0 || maximumPoolSize < corePoolSize)
> throw new IllegalArgumentException();
> {code}
> As a result, the first line of this part of the constructor of
> OrderedThreadPoolExecutor now throws an IllegalArgumentException.
> {code:java}
> super.setCorePoolSize(corePoolSize);
> super.setMaximumPoolSize(maximumPoolSize);{code}
