    • Mule 3.9.x requires Studio running on Java 8.

    • Mule 3.5.x requires Studio running on Java 7.

    • Other supported runtime versions work fine with both Java 7 or 8.

RHEL support is based on Eclipse support matrix. Learn more about Eclipse target environments.

Running real-time antivirus protection software on your operating system might have a negative impact on Anypoint Studio performance. Although this issue is prominent on Windows, it also occurs on Linux and macOS.

The steps to solve these performance issues vary depending on your antivirus software. A typical solution is to either allow or exclude the Anypoint Studio and Java executables, the Studio install and workspace filesystem locations, or some combination of both. See examples of solutions for Trellix Endpoint Security Threat Prevention, Windows Security, and Broadcom Endpoint Protection.
