Spring Boot - Async Processing

Why does this async method fail to catch exceptions?

@Async
public void runTask() {
  try {
    throw new IllegalStateException("Fail");
  } catch (Exception e) {
    System.out.println("Caught: " + e.getMessage());
  }
}

AExceptions are caught correctly; no failure occurs.

BThe exception is thrown outside the try block.

CAsync methods cannot have try-catch blocks.

DThe exception is swallowed by Spring async proxy before try-catch.

Step-by-Step Solution

Solution:

Step 1: Analyze try-catch inside async method
The exception is thrown inside the try block and caught immediately in the catch block.
Step 2: Confirm behavior
Since the exception is handled inside the method, no failure occurs due to uncaught exceptions.
Final Answer:
Exceptions are caught correctly; no failure occurs. -> Option A
Quick Check:
Try-catch inside async method works normally [OK]

Quick Trick: Try-catch inside async methods catches exceptions normally [OK]

Common Mistakes:

Assuming async proxy swallows exceptions before try-catch
Thinking try-catch is disallowed in async methods
Believing exceptions propagate despite catch
