This is a follow-up to PR #20273, which improves performance when the number of parameters exceeds 20.
When the number of parameters is large, the possibility of reuse will be lower, so we can use the static concat method and write the length and coder directly into the bytecode to solve the performance regression problem. ------------- Commit messages: - Optimize the construction of MethodType and MethodTypeDesc to reduce memory allocation - revert code style - from suggest - Update src/java.base/share/classes/java/lang/invoke/StringConcatFactory.java - support staticConcat Changes: https://git.openjdk.org/jdk/pull/20675/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=20675&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8338930 Stats: 159 lines in 3 files changed: 90 ins; 11 del; 58 mod Patch: https://git.openjdk.org/jdk/pull/20675.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/20675/head:pull/20675 PR: https://git.openjdk.org/jdk/pull/20675
