java 17, the spyK(map) does not work.

[lannyf77]

android project, having some unit test working fine until updated to java 17.
Here is a simplified test to show that the spyk(HashMap()) gets error

@Test
fun test_() {
        val metaMapSpy: MutableMap<String, String> = spyk(HashMap())
        every { metaMapSpy[any()] } returns null
        val ret = metaMapSpy["mLS"];
        assertEquals("should return null", null, ret)

}
using 
mockk 1.13.5
robolectric 4.10.2
java 17

class io.mockk.impl.InternalPlatform cannot access a member of class java.util.HashMap (in module java.base) with modifiers "transient"
java.lang.IllegalAccessException: class io.mockk.impl.InternalPlatform cannot access a member of class java.util.HashMap (in module java.base) with modifiers "transient"

with java 17, how to use mockk.spyK to mock a map?
