It is excluded on windows platforms, as of https://github.com/eclipse-openj9/openj9/issues/8208, but I think this error is a different one to the one that appears on aix

Start with java/lang/invoke/MethodHandlesSpreadArgumentsTest.java, especially the failure at line 152, and review the linked CI and TRSS reports for the ppc64 AIX run. Reproduce the AbstractMethodError on AIX and compare it with the existing Windows exclusion described in issue 8208. Done means the test no longer fails repeatedly on AIX and the regression is covered.
