Grinder contains output - unexpected argument '2048'

[pshipton]

Describe the bug
Running an internal grinder I noticed the following weird output, which didn't cause any failure.

13:04:35  expr: non-integer argument
13:04:35  expr: syntax error: unexpected argument '2048'
13:04:35  expr: syntax error: missing argument after '>'

To Reproduce
I'm running on Windows building openjdk running jdk_custom_0 with java/security/SecureRandom/ApiTest.java on a custom build of jdk11 (I don't expect the build matters). TKG_ITERATIONS is 3 and EXIT_FAILURE true. A machine label is set.

Test with ITERATIONS=3: Grinder

This issue seems machine-specific. It only happens on win19x86-rt2-1.fyre.ibm.com. I do not see the issue on win16x64rt-1-3.fyre.ibm.com

FYI I'm seeing this on the Temurin windows systems too at the time of writing e.g. https://ci.adoptium.net/job/Grinder/11520/console which used a custom target (not necessarily relevant)

This seems a common windows issue, not related with the parameters. not for grinder only. https://ci.adoptium.net/job/Test_openjdk21_hs_extended.openjdk_x86-64_windows_testList_1/32/consoleFull,
https://ci.adoptium.net/view/Test_openjdk/job/Test_openjdk21_hs_sanity.openjdk_x86-64_windows_testList_0/33/console

It happened to ubuntu before and was fixed #5350

The whole error message

At a guess I'd say it looks like bash specific syntax being used when the shell isn't bash.
