--------------------------------------------
Hi Guss,
you are right . Not setting the {{maximumPoolSize}} *before* setting the
{{corePoolSize}} will lead to an error in Java 10. I have applied your patch.
FTR, I also fixed a small mistake in the previous line :
{code:java}
if ((maximumPoolSize == 0) || (maximumPoolSize < corePoolSize)) {
throw new IllegalArgumentException("maximumPoolSize: " +
maximumPoolSize);
}
{code}
should be :
{code:java}
if ((maximumPoolSize <= 0) || (maximumPoolSize < corePoolSize)) {
throw new IllegalArgumentException("maximumPoolSize: " +
maximumPoolSize);
}
{code}
(the {{ThreadPoolExecutor.setMaximumPoolSize()}} method expect the
{{maximumPoolSize}} to be stricly positive :
{code:java}
public void setMaximumPoolSize(int maximumPoolSize) {
if (maximumPoolSize <= 0 || maximumPoolSize < corePoolSize)
throw new IllegalArgumentException();
...
{code}
> OrderedThreadPool implementation should be compatible with Java 10

>
> {{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}
