A regression is found in Java9+ creating String instance from UTF8 bytes, a side effect of string compactation https://openjdk.org/jeps/254 that changed the decoding logic. Specifically, when constructing a string from bytes:
``` String str = new String(largeBytes, StandardCharsets.UTF_8); ``` if the size of largeBytes is greater than 2^30 (>1 GB) but smaller than INT_MAX (2 GB), it fails on Java9+ (including 11, 17, 21, though the stack trace is slightly different, see below), regardless of jvm heap size. In Java8, it succeeded when jvm heap size is set to be sufficient. ------------- Commit messages: - Initial commit Changes: https://git.openjdk.org/jdk/pull/16974/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=16974&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8320570 Stats: 79 lines in 2 files changed: 72 ins; 0 del; 7 mod Patch: https://git.openjdk.org/jdk/pull/16974.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/16974/head:pull/16974 PR: https://git.openjdk.org/jdk/pull/16974
