This test validates several combinations of memory options for JFR. All test cases pass with 64bit builds and 32bit Client VM. However, one test case fails with 32-bit Server VM.

failed case JFR Options: -XX:FlightRecorderOptions=threadbuffersize=30m

The cause is an inability to allocate memory, which is easily reproduced with "jave -version."

```
$ java -server -XX:FlightRecorderOptions=threadbuffersize=30m -XX:StartFlightRecording -version
Started recording 1. No limit specified, using maxsize=250MB as default.

Use jcmd 8764 JFR.dump name=1 filename=FILEPATH to copy recording data to file.
openjdk version "1.8.0_442"
OpenJDK Runtime Environment (Temurin)(build 1.8.0_442-b06)
OpenJDK Server VM (Temurin)(build 25.442-b06, mixed mode)
# [ timer expired, abort... ]
```

This test case probably does not assume memory usage including heap space on 32-bit build.
