Fixed 2 flaky tests

[yesh385]

Created this PR to fix 2 flaky tests namely baseSynthesisAnnotationWorkTest which can be found here and getMethodsFromInterfaceTest which can be found here.

1. How was this test identified as flaky?
   This test was identifies as flaky by using an open-source research tool named NonDex which is responsible for finding and diagnosing non-deterministic runtime exceptions in Java programs.

2. What do the tests do?

• baseSynthesisAnnotationWorkTest
  It focuses on verifying the functionality related to annotations and annotated elements. Specifically, it involves retrieving and manipulating annotations associated with various classes and elements. The test also assesses the behavior of certain extension methods, as well as attributes and processors related to synthesized annotations.

• getMethodsFromInterfaceTest
  Confirms that when working with interfaces, calling getMethods directly retrieves all public methods. It obtains a total of four methods from TestInterface1, TestInterface2, and TestInterface3. The test then verifies that the results are identical when using getPublicMethods.

3. Why do the tests fail?

• baseSynthesisAnnotationWorkTest fails because there is a mismatch in the order of the synthesizedAnnotations which is obtained by calling the getAnnotations method and the expected order which is childAnnotation, grandParentAnnotation, parentAnnotation.
  The error occurs here:
  

  hutool/hutool-core/src/test/java/cn/hutool/core/annotation/GenericSynthesizedAggregateAnnotationTest.java

  Line 39 in 20f0c72

  Assert.assertEquals(

• getMethodsFromInterfaceTest fails because there is a mismatch in the order of methods and publicMethods which are obtained by calling the getMethods and getPublicMethods respectively.
  The error occurs here:
  

  hutool/hutool-core/src/test/java/cn/hutool/core/util/ReflectUtilTest.java

  Line 230 in 20f0c72

  Assert.assertArrayEquals(methods, publicMethods);

4. How I fixed these tests?

This PR fixes baseSynthesisAnnotationWorkTest by sorting the synthesizedAnnotations before comparing it with the expected order of childAnnotation, grandParentAnnotation, parentAnnotation.

This PR fixes getMethodsFromInterfaceTest by sorting both methods and publicMethods before checking that they are equal.

You can run the following commands to run the tests using NonDex tool:

mvn edu.illinois:nondex-maven-plugin:2.1.1:nondex -pl hutool-core -Dtest=cn.hutool.core.annotation.GenericSynthesizedAggregateAnnotationTest#baseSynthesisAnnotationWorkTest

mvn edu.illinois:nondex-maven-plugin:2.1.1:nondex -pl hutool-core -Dtest=cn.hutool.core.util.ReflectUtilTest#getMethodsFromInterfaceTest

(Optional) You can also run the following command to run the test:

mvn -pl hutool-core test -Dtest=cn.hutool.core.annotation.GenericSynthesizedAggregateAnnotationTest#baseSynthesisAnnotationWorkTest

mvn -pl hutool-core test -Dtest=cn.hutool.core.util.ReflectUtilTest#getMethodsFromInterfaceTest

Test Environment:

java version "1.8.0_202"
Apache Maven 3.6.3
