RandomSupport.AbstractSplittableWithBrineGenerator. makeSplitsSpliterator is intending to create a salt from a random long. The salt should have random letters of size 4 for each consecutive 4 bits and then the last 4 bits as ff, i.e. all bits set.
However the loop is never executed, the random bits are not used and the salt is always the same. This condition is false on the first execution: long multiplier = (1L << SALT_SHIFT) - 1; long salt = multiplier << (64 - SALT_SHIFT); while ((salt & multiplier) != 0) { This can be corrected by changing: while ((salt & multiplier) != 0) { to while ((salt & multiplier) == 0) { ------------- Commit messages: - Correct the loop condition Changes: https://git.openjdk.java.net/jdk/pull/5449/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=5449&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8273162 Stats: 1 line in 1 file changed: 0 ins; 0 del; 1 mod Patch: https://git.openjdk.java.net/jdk/pull/5449.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/5449/head:pull/5449 PR: https://git.openjdk.java.net/jdk/pull/5449
