Java™ 21 is real now. And so are virtual threads.
Everyone got excited about them, yet you prefer to keep your Java 8 job forever and you already have a nice plan to "accidentally" derail the migration to 21 by using virtual threads in a very, very unfortunate way. What a pity...
So you decided to come for this talk to look for some inspiration ;-)
Okay, please join us to learn how NOT to use virtual threads, and see the potential performance pitfalls of using them the wrong way.
