Summary: [JAVA][Test][Dataset]: Problem to get current reservation of JVM direct memory on macOS Big Sur Key: ARROW-15834 URL: https://issues.apache.org/jira/browse/ARROW-15834 Project: Apache Arrow Issue Type: Test Components: Java Affects Versions: 7.0.0 Reporter: David Dali Susanibar Arce Hi Team, Just compiling [java dataset |https://github.com/apache/arrow/tree/master/java/dataset]module it compile without problems but the test related to get current reservation of JVM direct memory is failing on my local machine macOS Big Sur 11.5.2. Command line: {code:java} mvn -Darrow.cpp.build.dir=../java-dist/lib clean install {code} Test code: {code:java} /** * Get current reservation of jVM direct memory. Visible for testing. */ @VisibleForTesting public long getCurrentDirectMemReservation() { try { final Class<?> classBits = Class.forName("java.nio.Bits"); final Field f = classBits.getDeclaredField("reservedMemory"); f.setAccessible(true); return ((AtomicLong) f.get(null)).get(); } catch (Exception e) { throw new RuntimeException(e); } } {code} Error message: {code:java} [ERROR] testDirectReservationListener Time elapsed: 0.028 s <<< ERROR! java.lang.RuntimeException: java.lang.NoSuchFieldException: reservedMemory at org.apache.arrow.dataset.jni.TestReservationListener.testDirectReservationListener(TestReservationListener.java:50) {code} If I changed from classBits.getDeclaredField("reservedMemory") to classBits.getDeclaredField("RESERVED_MEMORY") all the test finished without problems. Seeing this way to obtain reserved memory on [Jvm.java|https://github.com/OpenHFT/Chronicle-Core/blob/ea/src/main/java/net/openhft/chronicle/core/Jvm.java#L144]. Consider: Current test on macOS finished ok on the [ci workflows|https://github.com/ursacomputing/crossbow/runs/4987946390]. -- This message was sent by Atlassian Jira (v8.20.1#820001)
