What is the difference between memory leaks in Java programs on ARM and x86 architecture CPUs?

Analysis of memory leaks in Java programs under different CPU architectures

This article analyzes a case where Java programs exhibit different memory behaviors on ARM and x86 architecture CPUs: the same program, under the same UOS desktop system professional version, JDK version and OpenJFX version, only memory leaks on ARM architecture CPUs.

Because the operating system, JDK and OpenJFX versions are consistent, the problem does not stem from bugs or version differences in these components. Memory leaks are related to CPU architecture, which suggests that the problem may be related to the underlying hardware, drivers, or architecture-related system library interactions.

There are differences in memory management mechanisms between ARM and x86 architectures. The underlying implementation of OpenJFX may not be sensitive enough to these differences, resulting in the resources under the ARM architecture being not properly released, causing memory leaks. There may also be compatibility issues with drivers or system libraries for specific hardware, triggering memory leaks only on ARM architectures.

Ultimately, replacing the operating system solves the problem, which implies that the problem may be due to the operating system itself, or the interaction between the operating system and the Java running environment/OpenJFX under the ARM architecture is buggy. The new system environment eliminates this bug, thus resolving memory leaks. To determine the root cause, further analysis of system logs and memory usage is required.
