问题
Three weeks ago I had finished work on a web application. Everything was running without problems.
Now, three weeks later, having changed nothing(!!!), I wanted to run the application again but this time I got the following error message:
An error occurred while parsing the server response. Error message is: Provider org.glassfish.json.JsonProviderImpl not found
Exception in thread "main" com.michael.optimizer.exceptions.JsonException: This is a general JSON error. Check logs for details.)

回答1:
@Anish B.: javax.json dependency has the JsonProvider implementation class as dependency (as pointed out by Code_Mode) ... but (as pointed out by assylias), in fact not even the javax.json dependency is needed as the application server should provide this dependency.
回答2:
You are using javaee-web-api dependency and it has javax.json.spi.JsonProvider.class class file not the actual implementation.
You need to have the actual implementation of the JsonProvider. So add javax.json dependency. It has JsonProvider implementation class org.glassfish.json.JsonProviderImpl.class .
<!-- https://mvnrepository.com/artifact/org.glassfish/javax.json -->
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.json</artifactId>
<version>1.1.4</version>
</dependency>

I took dependencies from your pom.xml for testing.
I created my pom.xml.
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.michael</groupId>
<artifactId>optimizer</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>3.4.1</version>
</dependency>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>7.0</version>
</dependency>
</dependencies>
</project>
I checked whether it contains the necessary jars for this issue.
I used maven command : mvn dependency:tree. Using this command, you can see which jars and dependent jars are used.
These -> javax.json & javax.json-api artifacts are missing.
Add this dependency in pom.xml to ignore this error :
<!-- This jar provides the interfaces -->
<!-- This may be optional as javaee-web-api contains JsonProvider.class -->
<!-- But still I will recommend to add this explicitly for you to be at safer side -->
<dependency>
<groupId>javax.json</groupId>
<artifactId>javax.json-api</artifactId>
<version>1.0</version>
</dependency>
<!-- This jar provides the implementation of this interfaces
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.json</artifactId>
<version>1.1.4</version>
</dependency>
Note :javax.json-api implementation is done by javax.json.
