> Backporting JDK-8318811: Compiler directives parser swallows a character after line comments. Fixes JSON::skip_line_comment() to match specification and "return the first token after the line comment without consuming it" by using `peek` instead of `next`. Adds test. Ran GHA Sanity Checks, local Tier 1 and 2, and new `test/hotspot/jtreg/compiler/compilercontrol/parser/DirectiveParserTest.java` tests. Patch is clean.
