Toolbox App 3.7 enables JVM memory optimizations by default and fixes Windows Smart App Control compatibility

Toolbox App 3.7 shifts JVM memory management from an opt-in feature to a default configuration. The change applies to garbage collection, code-cache behavior, and memory allocation without requiring user intervention. This reduces the risk of excessive memory consumption in long-running IDE sessions, though the optimizations may not eliminate all edge cases in custom JVM setups or large monorepo projects. Engineers who previously disabled these settings will need to re-evaluate their overrides after updating.

The update addresses a specific compatibility issue with Windows Smart App Control, a security feature that blocks unsigned or suspicious applications. Earlier versions of the Toolbox App failed to launch under this setting, forcing users to disable the control or whitelist the app manually. The fix removes this friction for enterprise environments where Smart App Control is enforced, but it does not extend to other Windows security features like Defender Application Control or third-party endpoint protection tools.

Patch updates on macOS now include code signature verification for IDE bundles. The Toolbox App checks the updated bundle’s signature and removes any runtime files not sealed by the new build. If verification fails, it downloads a clean copy of the IDE. This prevents corruption from partial updates or filesystem errors but adds a small delay to the update process. The change does not affect Linux or Windows installations, where patching mechanisms remain unchanged.

Session expiration handling has been improved for temporary network interruptions, a common issue in corporate networks or VPN environments. The fix reduces false positives but does not address all possible causes of session expiration, such as token revocation or account policy changes. Users who still encounter the issue are encouraged to report it, suggesting that the root cause may involve interactions with JetBrains’ authentication services rather than the Toolbox App alone.
