Launching Java from a bundled JRE in macOS app
Hi there! I am trying to build a macOS app using Electron. There is a feature on the app that depends on a http server to run locally. This Server was built using Java. Both the compiled server and the Java Runtime Environment were bundled in the build. To start the server I use NodeJS's child_process.spawn, pointing the bundled JRE's executable and the server implementation. The issue I am facing is that the Java Virtual Machine is not starting. It returns the following error message: Error: Port Library failed to initialize: -1 Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. Both the JRE and the server are located in Contents directory, in a subdirectory I have created for them. Here are the app's entitlements: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.application-groups</key> <string>REDACTED</string> <key>com.apple.application-identifier</key> <string>REDACTED</string> <key>com.apple.developer.team-identifier</key> <string>REDACTED</string> <key>com.apple.security.cs.allow-jit</key> <true/> <key>com.apple.security.cs.allow-unsigned-executable-memory</key> <true/> <key>com.apple.security.cs.allow-dyld-environment-variables</key> <true/> <key>com.apple.security.cs.disable-executable-page-protection</key> <true/> <key>com.apple.security.cs.disable-library-validation</key> <true/> <key>com.apple.security.network.client</key> <true/> <key>com.apple.security.network.server</key> <true/> <key>com.apple.security.device.microphone</key> <true/> <key>com.apple.security.device.audio-input</key> <true/> <key>com.apple.security.device.camera</key> <true/> <key>com.apple.security.print</key> <true/> <key>com.apple.security.files.user-selected.read-write</key> <true/> <key>com.apple.security.temporary-exception.files.absolute-path.read-write</key> <true/> </dict> </plist> Here the entitlements inherit: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.inherit</key> <true/> </dict> </plist> Is there any missing step to allow the spawning of this process?

Spawn java process from sandboxed macOS app
Hi there! I am trying to publish a macOS app on App Store, thus the app must be sandboxed. The app is built with Electron and electron-builder. A tool of the app needs to run a local web server, to do so a java runtime and a .jar file are downloaded during runtime and the server is started using spawn. In the MAS version of the app, running from TestFlight, I get EPERM error when spawn is called. Both java's runtime and .jar are downloaded to app's container. I have tried also downloading them to outside the container (by saving them in the directories that are symlinked to outside of it) by I get the same error. How could I solve that issue?
