@himanshug You are right that JVM as a multi-platform should just run on any of the supported platforms. The testing on ARM64 architecture adds some confidence that the software does actually run on that platform. Druid itself could be pure Java project but it may depend on a third party library that uses native libraries. For example Apache Pig failed to run on aarch64 because it was using old version of Snappy library (compression) that didn't provide aarch64 native library (.so). Another possible problem could arise if your Java project uses some JDK APIs which hit some corner case that is not covered for aarch64. The JDK has a lot of tests but no project has 100% coverage! As any other maintained project the JDK project constantly evolves and regressions happen. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
