Prevent garbage collection during critical path execution?

Question

Java

Hello.
Task: there is a desktop application that periodically exchanges information with industrial controllers via Modbus RTU, and it is important that stop-the-world does not occur at the time of the exchange of messages.
Is it possible in Java (JVM Hotspot) to disable garbage collection during critical path execution?

Answer 1

No. Do not try. It has been repeatedly discussed on stackoverflow and other places. For example: stackoverflow.com/questions/12847151/setting-xxdis...
