Hi. I'm interesting in this issue.
I can't reproduce this case.

 

Here's my code.
{code:java}
public static class TestBean {
    public String fooVarArgs(final String... s) {
        return "fooVarArgs(String...)";
    }
}{code}
{code:java}
@Test
void temp() {
    Method fooVarArgs = MethodUtils.getMatchingAccessibleMethod(TestBean.class, 
"fooVarArgs");
    assertNotNull(fooVarArgs); // just passed.
} {code}
working on
 * latest master branch.
 * jdk 17
