the method is below:

@Test
    void t202306261048() throws OgnlException {
        // buile OgnlContext
        final String ddd = "ddd";
        OgnlContext context = (OgnlContext) Ognl.createDefaultContext(ddd);

        // root set
        context.setRoot(ddd);

        StringUtils.equalsAny("dd", new String[]{"dd","aa"});
        System.out.println(Ognl.getValue(Ognl.parseExpression("@org.apache.commons.lang3.StringUtils@equalsAny('dd',new String[]{'dd'})"), context, context.getRoot()));
    }

Shouldn't you use java.lang.String like this

"@org.apache.commons.lang3.StringUtils@equalsAny('dd',new java.lang.String[]{'dd'})"

?

I tried and got the same error. It's seem because of the varargs method. After I delete the if (method.isVarArgs()){} block in method ognl.OgnlRuntime#callAppropriateMethod , I got the right result.

@lianyiwuming ,

Are you aware that you don't need to create the array explicitly?

"@org.apache.commons.lang3.StringUtils@equalsAny('cc', 'dd', 'ee')"

[lianyiwuming]

@harawata oooh,yes, you are right, thx

[lukaszlenart]

Does this fix the problem?

[lianyiwuming]

Yes! It work when I use varargs instead of the array explicitly. @lukaszlenart
