PHP 8 as it is actually written now: enums, readonly, constructor promotion, property hooks and match; the comparison and array semantics that changed under you; and the security defaults — PDO emulation, unserialize, escaping, randomness, password hashing — that decide whether the application is exploitable.
Java as it is written on a current LTS, not as it was written in 2014. Records, sealed types and pattern matching; virtual threads and what still pins them; the concurrency and equality contracts that fail silently; java.time, BigDecimal and the numeric traps; and the JDK APIs that are insecure by default until you configure them.
Writing C that does not have a CVE in it. Memory safety, the undefined behaviour a modern optimiser will exploit, the standard-library functions whose signatures lie about what they do, integer promotion and overflow, and the build flags and sanitizers that catch what review misses.
