Unable to Apply Ground Truth Patch

[danielding110]

After checking out Cli-18, I attempted to apply the ground truth patch provided in the defects4j repo. I switched the - to + in order for the patch to patch the buggy code. After that, I ran with the following command: patch src/java/org/apache/commons/cli/PosixParser.java 18.src.patch Which failed with the following messages: patch: **** malformed patch at line 21: - }

Similar problem happens to other multi-hunk problems like Time-3, but the patch works fine for single hunk bugs like Cli-27.
