<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1"><span style="font-family:"Courier New"">When subclassing StructuredTaskScope I always have to @Override `join` and `joinUntil` to return my subclass type to provide a fluent api.<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1"><span style="font-family:"Courier New"">When subclassing StructuredTaskScope @Override `handleComplete` I find myself wanting to write a switch expression on Subtask#state(), but if
I do, I always need to have a case for UNAVAILABLE and throw IllegalStateException.<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1"><span style="font-family:"Courier New"">Using StructuredTaskScope (no subclassing) feels weird because you must decide to use either the `<>` diamond operator to allow any types or
define a type T for restricting subtasks (makes you wonder if you are using it correctly). Whereas, both ShutdownOnFailure and ShutdownOnSuccess just feel right to use.<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1"><span style="font-family:"Courier New"">In IntelliJ the Javadoc of StructuredTaskScope doesn’t seem to properly format and makes it very difficult to read (probably an issue with IntelliJ).<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1"><span style="font-family:"Courier New"">Blocking IO is not interruptible and this can cause confusion when the scope won’t close in a timely manner even though something may have already
thrown an exception (probably falls under the Non-Goal of thread cancellation mechanism). e.g. 2 calls to fork one reading a short file and the other reading an long file, short one fails, if I don’t do something to close the long file stream I will read the
whole thing (making ShutdownOnFailure not really live up to its name).<o:p></o:p></span></li></ul>

<p class="MsoNormal"><span style="font-family:"Courier New"">I love that StructuredTaskScope interrupts threads on close/shutdown (it allows some short-circuiting that I struggled with when using Executors.newVirtualThreadPerTaskExecutor()). Here is my new
