Analyzer::Java::Cli

commons-cli (no subcommands; flags on root).

Current (non-deprecated) addOption(String opt, boolean hasArg, String description) overload used for short-only flags. The true|false literal gate in the 2nd argument position guarantees this never overlaps with ADD_OPTION_LL above (which requires a quoted string there), so a given call is matched by exactly one of the two.

jopt-simple (no subcommands; flags land on root, like commons-cli). .accepts("flag")/.acceptsAll(List.of("f","flag")) are only real CLI flags when called on a variable that was actually bound to new OptionParser(...) — jopt-simple's OptionParser isn't the only class with an accepts(...) method (e.g. a FormatMatcher.accepts(fmt) helper), so the receiver is tracked per-file in the same forward pass and matches on an untracked receiver are dropped rather than attributed to the root command.

Cheap pre-gate applied to the RAW file, before the comment strip.

strip_comments materialises an Array(Char) of the whole file and rebuilds it character by character; running it on all 8,658 .java files in spring-boot to then reject 97% of them on the gate below was the bulk of this analyzer. Stripping only replaces characters with ' ' or '\n' and never changes the character count, so a literal with no whitespace in it can appear in the stripped text only if it already appears, unchanged, in the raw text. Each alternative of the real gate requires one of these literals verbatim (the new\s+X forms require X; the \s-carrying parts are deliberately not relied on, since blanking a comment can manufacture whitespace). Files that pass still go through the full, comment-aware gate.

Instance-side view of the same declaration. The per-file rescues live on this base class, which has no way to name the analyzer that is running inside them, so a skipped file could not be attributed to a tech. Deriving it from analyzer_for keeps the name written exactly once.
