Provenance Record

Excellent technical News article at 672 words (within 400-1200 range). Comprehensive coverage of all 10 JEPs with well-organized subsections. The article balances headline features (HTTP/3, AOT caching) with smaller standard library additions and preview feature status updates.

All 3 sources fetched and verified. Source 1 (openjdk.org): Official JDK 26 project page. Confirms all 10 JEPs by number and title, release schedule (GA March 17, 2026), release-candidate phase. ✅ Source 2 (infoq.com): Confirms JDK 25 predecessor, feature freeze in early December 2025, AOT caching GC-agnostic improvements (JEP 516), Structured Concurrency sixth preview (JEP 525), 10 JEPs across categories. ✅ Source 3 (foojay.io): Confirms JEP 500 final field mutation modes (allow/warn/debug/deny), JEP 504 Applet API removal, standard library additions (UUIDv7, Process AutoCloseable, string case-folding, BigInteger nth root), PEM second preview, Lazy Constants second preview, no features graduated from preview. ✅

All major claims verified. JEP numbers and titles match the official OpenJDK page exactly. Release date, feature freeze timing, RC phase, and preview counts all confirmed. One minor observation: the article states 'saturating arithmetic on Instant' in the standard library additions list, but the foojay source reports saturating methods on Duration (plusSaturating with boundary clamping). This may be a minor imprecision — both types may have received new methods, but the source specifically mentions Duration. Not significant enough to block publication. The 'PEMRecord renamed to PEM' detail in JEP 524 cannot be verified from the source extracts but is a plausible technical detail from the full JEP text.

High-quality technical News article with comprehensive JDK 26 coverage sourced from the official OpenJDK site and reputable Java community publications. All 10 JEPs accurately described. One very minor potential imprecision (Instant vs Duration for saturating arithmetic) does not materially affect the article. Ready for publication.
