ConstantBootstraps.explicitCast behaves like a snippet of code in its specification. However, in the rest of the nominal spec, it incorrectly assumes a null `value` and a primitive `dstType` results in a ClassCastException instead of the zero value of that primitive type. This is inconsistent with that snippet and the actual code behavior.
The specification is fixed, the test for `explicitCast` is merged into the main `ConstantBootstraps` test, and a new unit test case for `value = null` and `dstType = char.class` is added, verifying the outcome is `'u0000'`. ------------- Commit messages: - Update and consolidate tests - 8364751: ConstantBootstraps.explicitCast violates doc contracts for null-to-int Changes: https://git.openjdk.org/jdk/pull/26714/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=26714&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8364751 Stats: 131 lines in 3 files changed: 43 ins; 79 del; 9 mod Patch: https://git.openjdk.org/jdk/pull/26714.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/26714/head:pull/26714 PR: https://git.openjdk.org/jdk/pull/26714
