SpringBoot 1.4.x compatibility with Java 11 [duplicate]

I'm using 1.4.1.RELEASE of spring-boot application. Everything was working ok for Java 8. However when I updated java version to 11 I can't run application using command mvn clean spring-boot:run. At the same time I can package is successfully (using mvn package). When I set java version to 8, it's working fine again.

I can understand that newer versions of Spring might require newer version of Java. But it's not clear why older spring-boot can't be run on newer java versions.

The version of Spring Boot that you're using was released in September, 2016, long before Java 11 was released in September, 2018. I recommend you update to the latest version of Spring Boot, which is currently 2.1.9.
Please let me know if this fixes your issue; otherwise, we'll debug it further.

By default, Spring Boot 1.4.1.RELEASE requires Java 7 until Java 8 which is highly recommended and Spring Framework 4.3.3.RELEASE or above. If you want to use Java 11 with some version of Spring Boot, The latest version is recommended to use, then you should do a upgrade your project.
Although you can use Spring Boot with Java 6 or 7, we generally recommend Java 8 if at all possible.
System Requirements for Spring Boot 1.4.1
The version of Spring Boot which starts to use Java 11 it was 2.1.1 then you can use any up to this version.
Spring Boot 2.1.1.RELEASE requires Java 8 and is compatible up to Java 11 (included).
System Requirements for Spring Boot 2.1.1

Spring Boot 2.1.1.RELEASE fails starting due to Hystrix and gradle upgrade?

we recently updated Spring boot from 1.3.7.RELEASE to Spring Boot 2.1.1.RELEASE
and also we are upgrading java7 to Java11(Open amazon-corretto-11.jdk) and also we upgraded the gradle distribution version from Gradle 2.10 to Gradle 5.3 as well.
Note: we have dependancy for hystrix as well ,
and when we specify the Hystrix
version as 1.1.7.RELEASE.
Code compiles fine but failed to start the application with below error:
compile ("org.springframework.cloud:spring-cloud-starter-hystrix:1.1.7.RELEASE")
compile "org.springframework.cloud:spring-cloud-starter-hystrix-dashboard:1.1.7.RELEASE"
Error: o.s.boot.SpringApplication - Application run failed
java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder.([Ljava/lang/Object;)
Can anyone help us on this issue? prompt response will be appreciated.

spring-cloud-starter-hystrix 1.1.7 is built for Spring Boot 1, it's from 2016. If you upgrade Spring Boot, you need to upgrade all the related dependencies too.
I highly suggest you don't upgrade to a really old version of Spring Boot 2.1, upgrade directly to Spring Boot 2.1.12.RELEASE so you have all the necessary bug and CVE fixes. And pick a hystrix dependency which belongs to Spring Boot 2.1.x, which likely is spring-cloud-starter-netflix-hystrix 2.1.5.

Downgrade embedded tomcat version in maven

My Springboot application was build in tomcat 9.0 with java version of 1.8 and our server has tomcat 6 with java version of 1.7. I have already downgrade our java version in facet.
How can i downgrade the embedded tomcat in maven? Do I need to generate a new initialize from springIO?

From the SpringBoot docs:
Spring Boot 2.1.1.RELEASE requires Java 8 and is compatible up to Java
11 (included). Spring Framework 5.1.3.RELEASE or above is also
required.
https://docs.spring.io/spring-boot/docs/2.1.1.RELEASE/reference/htmlsingle/#getting-started-system-requirements
So if you must stay on 1.7 and Tomcat 6, you'll need to move away from SpringBoot and back to your older solutions.

migrating JDK 1.8 to JDK 1.9 for Spring 3.2 x framework based on large scale enterprise application

I have a spring 3.2.x application using iBATIS and tiles 3.0.x .it is running in JDK 1.8 without any issues.I am trying to migrate it to JDK 1.9.
If I migrate JDK 1.8 to JDK 1.9 What are the steps I need to follow?should I need to be upgrade spring 4.2.x jars?

should I need to be upgrade spring 4.2.x jars?
As far as i know Spring framework 5 released specially for java 9 with full compatibility. So you should use that for better results..!!

How to choose the right JDK JavaEE Spring version

Generally I will use the following framework in my project: Spring MVC + Hibernate with Tomcat as the container.
And I never care about the version, the later the better.
This is the concrete SDK, framework version in the project:
JDK 1.7
Spring Framework:
spring-webmvc >> 4.1.6.RELEASE
Hibernate:
hibernate-entitymanager >> 4.3.10.Final
org.hibernate.javax.persistence >> hibernate-jpa-2.1-api >> 1.0.0.Final
Tomcat 7
The application works well under tomcat, however I meet some problems when I deploy the application from Tomcat to a Java EE Server(which support JavaEE 5 only).
One of the error I got is something like:
java.lang.NoSuchMethodError: javax.persistence.Table.indexes()
It seems that the indexes is a new method in JPA2.1(which is supported in JavaEE 7) while the Java EE server does not provide it.
But as shown, the hibernate dependency org.hibernate.javax.persistence >> hibernate-jpa-2.1-api >> 1.0.0.Final provide the methods, why the Java EE Server can not use that?
And to solve the problme, for a given JavaEE Server say it support JavaEE 5 only, what should be under consideration when choosing JDK, frameworks?

JPA 2.1 is for JavaEE7 and Java 7 onwards.
For JavaEE compatibity with JDK versions, I would take a look at this previous StackOverflow question.
