      `Method::isVarArgs` of a dynamic proxy method may return `true` if the method declared in a proxy interface has `ACC_VARARGS` flag set. In previous releases, all dynamic proxy methods do not have `ACC_VARARGS` flag set. No impact to existing applications invoking such methods at runtime. This compatibility risk of this behavioral change is expected to be low.

    Description

      Summary

      Method::isVarargs of a dynamic proxy generated method should match the proxy interface method.

      Problem

      ACC_VARARGS flag of all dynamic proxy generated methods are always not set even if the method declared in a proxy interface takes a variable number of arguments set.

      Solution

      If ACC_VARARGS flag of a proxy interface method is set, the generated method in the proxy class has the ACC_VARARGS flag set.
      If there are two or more proxy interfaces declaring such a method, it matches the method declared in the first proxy interface.

      Specification

      This CSR documents a behavioral change. No spec change.
