Unable to run application due missing asset.notNull method

Bug report

Application built with spring boot version 2.0.0-BUILD-SNAPSHOT cannot start due missing Assert.notNull(single argument) method

java.lang.NoSuchMethodError: org.springframework.util.Assert.notNull(Ljava/lang/Object;)V
	at org.springframework.boot.bind.PropertiesConfigurationFactory.<init>(PropertiesConfigurationFactory.java:92) ~[spring-boot-2.0.0.BUILD-20170130.202942-338.jar:2.0.0.BUILD-SNAPSHOT]

It's an intentional change
spring-projects/spring-framework@1b2dc36

[spencergibb]

A boot update is coming shortly.

[yeta-io-ceo]

Such major code changes better to publish with backward compatibility.

[yeta-io-ceo]

If it possible to push a quick fix that adds old method (with deprecation warning)? Without it I can't run any project that uses latest spring boot.

As Spencer pointed out, this change was committed in Spring Framework only a couple of hours ago. Thanks for working with our SNAPSHOTs, please bear with us while we're fixing this across the Spring portfolio.

@yeta-io spring 5 is making breaking changes. There are going to be incompatibilities.

@yeta-io Unless you're developing features for Spring Boot itself we wouldn't recommend using SNAPSHOT versions. You should only be using .RELEASE versions for production.
