is it okay to throw exceptions in a synchronized block?

[ephemient]

if it makes sense to

[y]

as in, it's safe: no hidden gotchas to be aware of

[ephemient]

it's basically

try {
    MONITORENTER
    block()
} finally {
    MONITOREXIT
}

(you can't write those bytecode instructions in pure Kotlin but the compiler can)

[y]

oh. yeah that's as clear as I can hope for, as a person who knows basically nothing about the jvm.

In such constructs, the finally block always executes, whether the try block completed normally or threw an exception. You can read about try-catch-finally constructs in this section of the Java documentation:

And more specifically about `finally`:
