Removes the remaining overhead in cascading, container elements and executable validation. - **Container elements:** each element's leaf container element descriptors are precomputed as a flat array. The runtime container key is cached per container class, instead of resolving type arguments reflectively for every cascaded container. Extracted values are collected without a `Lazy` holder. - **Ancestor lookup:** the ancestor of a cascaded container element is found by comparing paths in place, without materializing the element's path. - **Cascading:** single-group strategies without group conversions are cascaded directly, and container elements are cascaded without a capturing lambda per value. - **Executables:** descriptors are cached per `Executable` instead of hashing a new `Signature` twice per call. The executable's base path and the bean's `Default` group redefinition are reused, parameter frames are created without streams, default parameter names are cached, and wrapper types map to primitives with a lookup instead of a scan. Biggest effects: `executableParameters` 3.8×, `cascadedCycles` 3.2×, `cascadedList` 2.8×, `deepGraph` 2.5×, `containerElements` 2.3×, `executableReturnValue` 1.8×. A few rows (`wideBeanInvalid`, `elMessage`) are lower in this run with unchanged allocation, which points to noise. ### Benchmarks (vs. #274) Measured with JMH 1.37 on JDK 25 (`-p provider=bval -f 2 -wi 2 -i 3`, 1 s iterations, `-prof gc`) against the PR below this one in the stack. This was a busy desktop machine, so throughput carries large error bars (shown as ±). The allocation column (B/op) is deterministic and more reliable. | Benchmark | Before | After | Change | B/op before → after | |---|---:|---:|---:|---:| | cascadedCycles (ops/ms) | 5.52 ± 74% | 17.5 ± 13% | **3.16×** | 443,567 → 214,013 | | cascadedList (ops/ms) | 1.57 ± 23% | 4.36 ± 10% | **2.78×** | 2,043,592 → 882,730 | | classLevelInvalid (ops/ms) | 2,780 ± 53% | 3,123 ± 21% | **1.12×** | 1,232 → 1,232 | | classLevelValid (ops/ms) | 5,027 ± 34% | 6,903 ± 22% | **1.37×** | 568 → 568 | | composedInvalid (ops/ms) | 2,016 ± 97% | 2,729 ± 33% | **1.35×** | 1,232 → 1,232 | | composedValid (ops/ms) | 2,832 ± 83% | 3,925 ± 43% | **1.39×** | 800 → 852 | | containerElements (ops/ms) | 4.99 ± 80% | 11.4 ± 27% | **2.29×** | 391,370 → 283,097 | | deepGraph (ops/ms) | 345 ± 45% | 850 ± 55% | **2.46×** | 4,008 → 3,360 | | elMessage (ops/ms) | 1,154 ± 44% | 1,009 ± 28% | **0.87×** | 2,088 → 2,096 | | executableParameters (ops/ms) | 564 ± 52% | 2,125 ± 11% | **3.77×** | 3,689 → 1,717 | | executableReturnValue (ops/ms) | 1,258 ± 60% | 2,226 ± 23% | **1.77×** | 1,817 → 1,401 | | explicitGroup (ops/ms) | 4,462 ± 53% | 5,199 ± 11% | **1.17×** | 698 → 698 | | mixedDrivers (ops/ms) | 3,588 ± 4% | 3,530 ± 9% | **0.98×** | 1,041 → 1,041 | | validateProperty (ops/ms) | 2,983 ± 10% | 3,009 ± 5% | **1.01×** | 1,316 → 1,292 | | validateValue (ops/ms) | 6,487 ± 9% | 5,899 ± 27% | **0.91×** | 648 → 636 | | wideBeanInvalid (ops/ms) | 267 ± 11% | 197 ± 88% | **0.74×** | 9,568 → 9,528 | | wideBeanValid (ops/ms) | 825 ± 10% | 720 ± 17% | **0.87×** | 2,816 → 2,816 | | Jsr303Benchmark.bvalBootstrapAndValidate (ops/s) | 2,880 ± 56% | 2,284 ± 51% | **0.79×** | 247,317 → 248,388 | | Jsr303Benchmark.bvalBuildFactory (ops/s) | 11,763 ± 3% | 11,070 ± 12% | **0.94×** | 88,397 → 88,753 | | Jsr303Benchmark.bvalConstraintsFailure (ops/s) | 3,370,311 ± 10% | 2,849,765 ± 20% | **0.85×** | 1,352 → 1,352 | | Jsr303Benchmark.bvalConstraintsFailureReuseValidator (ops/s) | 2,876,706 ± 16% | 3,121,360 ± 4% | **1.09×** | 1,376 → 1,384 | | Jsr303Benchmark.bvalConstraintsSuccess (ops/s) | 13,015,631 ± 35% | 12,273,725 ± 29% | **0.94×** | 432 → 432 | | Jsr303Benchmark.bvalConstraintsSuccessReuseValidator (ops/s) | 13,263,502 ± 19% | 14,058,074 ± 9% | **1.06×** | 432 → 432 | | Jsr303Benchmark.bvalNoConstraints (ops/s) | 167,339,787 ± 11% | 158,038,315 ± 11% | **0.94×** | 0 → 0 | | Jsr303Benchmark.bvalNoConstraintsReuseValidator (ops/s) | 187,581,916 ± 24% | 186,538,080 ± 12% | **0.99×** | 0 → 0 | -- This is an automated message from the Apache Git Service.
