      Description

      ADDITIONAL SYSTEM INFORMATION :
      OS:
      Windows 10 Pro, 21H1

      JAVA:
      openjdk 11.0.13 2021-10-19
      OpenJDK Runtime Environment 18.9 (build 11.0.13+8)
      OpenJDK 64-Bit Server VM 18.9 (build 11.0.13+8, mixed mode)

      A DESCRIPTION OF THE PROBLEM :
      I ran into the same issue as https://bugs.openjdk.java.net/browse/JDK-8229376. The example there is still valid and compilation fails with openjdk 11.0.13 2021-10-19:

      compiler message file broken: key=compiler.misc.msg.bug arguments=11.0.13, {1}, {2}, {3}, {4}, {5}, {6}, {7}

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Compile provided example.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Compiler should compile.
      ACTUAL -
      Compiler does not compile

      ---------- BEGIN SOURCE ----------
      import java.util.Set;

      import org.springframework.boot.SpringApplication;
      import org.springframework.boot.autoconfigure.SpringBootApplication;
      import org.springframework.core.ParameterizedTypeReference;
      import org.springframework.http.HttpMethod;
      import org.springframework.http.ResponseEntity;
      import org.springframework.web.client.RestTemplate;


      @SpringBootApplication

      ResponseEntity<T> execute();

      public Set<String> getResult() {
      Set<String> response;
      response = callApi(() -> restTemplate.exchange(
      "/abc",
      HttpMethod.GET,
      null,
      new ParameterizedTypeReference<>() {
      }));
      return response;
      }

      public <T> T callApi(final ApiCall<? extends T> apiCall) {
      return apiCall.execute().getBody();
      }

      public static void main(String[] args) {
      SpringApplication.run(Jdk11bugApplication.class, args);
      }
      }
      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Provide explicit type definition to ParameterizedTypeReference instantiation:
      new ParameterizedTypeReference<Set<String>>() {}

      FREQUENCY : always
