The manual test Cipher/DES/PerformanceTest.java fails with ArithmeticException due to potential division by zero. The issue arises when calculating the elapsed time using end - start, which could result in zero milliseconds if start and end are identical due to the high speed of execution. This leads to a division error in the following code snippet:
start = System.currentTimeMillis(); end = System.currentTimeMillis(); int speed = (int)((data.length * count)/(end - start)); The fix is to provide a default value in case _end_ is not higher than _start_. ------------- Commit messages: - remove unused imports - tiny refactor - avoid dividing by zero Changes: https://git.openjdk.org/jdk/pull/20135/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=20135&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8336240 Stats: 7 lines in 2 files changed: 2 ins; 3 del; 2 mod Patch: https://git.openjdk.org/jdk/pull/20135.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/20135/head:pull/20135 PR: https://git.openjdk.org/jdk/pull/20135
