Hi all,

I=E2=80=99m trying to run multiple JMeter test plans in parallel using Java
threads, where each thread creates a new StandardJMeterEngine object
and executes a different test.

However, I=E2=80=99m facing an issue with FileServer. It appears to be a
singleton and shared across all executions. As a result, when one test
completes early, it calls FileServer.getFileServer().closeFiles(),
which causes file-related errors in the other ongoing tests (e.g.,
missing CSV files).

I=E2=80=99d like to know:

Is running multiple JMeter tests in parallel like this (multiple
StandardJMeterEngine objects in the same JVM using threads) a
supported use case?

If not, is the correct approach to launch each test in a separate JVM
(e.g., via ProcessBuilder)?

Is there a way to isolate or override FileServer usage per test so
that one doesn't affect the others?

Any suggestions or guidance would be really helpful.

Thanks,
Sruthika
