DirectoryProcessor catches InterruptedException without restoring interrupt flag — silent thread-pool shutdown breakage

[tsushanth]

Bug description

sentry/src/main/java/io/sentry/DirectoryProcessor.java lines 94–96 catch Throwable in the outer try-catch, which swallows InterruptedException without restoring the interrupt flag:

} catch (Throwable e) {
  options.getLogger().log(SentryLevel.ERROR, "Failed to process directory.", e);
  // InterruptedException reaches here — interrupt flag is cleared and never restored
}

When the enclosing thread pool calls shutdownNow(), the worker thread's interrupt is set, but processDirectory() catches and discards it. The thread continues running, the pool's awaitTermination() never unblocks, and shutdown silently hangs.

Fix

Restore the interrupt flag when the caught exception is an InterruptedException:

} catch (Throwable e) {
  options.getLogger().log(SentryLevel.ERROR, "Failed to process directory.", e);
  if (e instanceof InterruptedException) {
    Thread.currentThread().interrupt();
  }
}

@tsushanth any reason for opening this up? this seems to be a dup of #5849 which you opened two days ago.
