“Can I block here?” With #Java26, the answer is increasingly yes. #VirtualThreads & #StructuredConcurrency reduce the need for callback-heavy code & oversized thread pools.

Damiana Nascimento explains what modern #JVM-first design looks like: https://javapro.io/2026/05/06/java-26-in-practice-how-the-jvm-is-changing-the-way-we-write-code/

Thread leakage is the silent killer of “quick parallelization.” #StructuredConcurrency makes sure child tasks end with the parent scope—by design.

#Concurrency bugs rarely fail loudly — they leak resources, stall requests, & waste CPU. @BalaRawool demonstrates how #StructuredConcurrency can short-circuit failures and keep workflows consistent in #SpringBoot.

Ok, to follow up on yesterday's structured concurrency question:

In Python, I have a hypothetical HTTP client:

async with HTTP() as client:
http.get("https://site.example/index.html")

and it handles things like HTTP/2 multiplexing and connection pools and stuff. So it needs some background tasks to coordinate and maintain them.

Classically, I'd call these "daemon tasks" (after Python's daemon threads).

But I feel like I'm missing something?
