> {{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}
