The first call to `WideCharToMultiByte()` returns the required size for the multibyte buffer. When it returns 0, `exit(1)` is issued inside `JLI_MemAlloc()`. If the second call to `WideCharToMultiByte()` returns 0, it is explicitly dealt with the patch which also issues `exit(1)`. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/20428#discussion_r1702160635
