Originally Reported in OpenJ9, fix by @AditiS11 present here:
https://github.com/ibmruntimes/openj9-openjdk-jdk25/pull/32
These test failure were reported in OpenJ9 (x86), I can't reproduce on my
system (s390x):
java/foreign/TestFill.java
java/foreign/TestSegments.java
java/foreign/TestSegmentBulkOperationsContentHash.java
java/foreign/TestStringEncoding.java
java/foreign/TestVarArgs.java
```java
// Always allocate at least some memory so that zero-length segments
have distinct
// non-zero addresses.
alignedSize = Math.max(1, alignedSize);
Here minimum-allocated size will be 1, which is incorrect because
private static void initNativeMemory(long address, long byteSize) {
for (long i = 0; i < byteSize; i += Long.BYTES) {
UNSAFE.putLongUnaligned(null, address + i, 0);
}
}
`initNativeMemory()` is going to write Long.
-------------
Commit messages:
- update min size to Long.BYTES
