is it okay to throw exceptions in a

synchronized

block?

if it makes sense to

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

it's basically

try {
    MONITORENTER
    block()
} finally {
    MONITOREXIT
}

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

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: https://docs.oracle.com/javase/tutorial/essential/exceptions/handling.html And more specifically about `finally`: https://docs.oracle.com/javase/tutorial/essential/exceptions/finally.html
