spring-boot: Devtools: Same class with different classloader causing NoSuchBeanDefinitionException
@philwebb I have started to check our applications and came across an issue. (Sorry if It is already fixed)
Short description: My applications can not find some of beans when application starts.
Detailed description: I have debugged and found that If a class is loaded with two different class loader, the java.lang.Class#isAssignableFrom seems can not handle correctly. This is causing a problem in org.springframework.util.ClassUtils#isAssignable which is used for bean comparison. As a result a bean not found exception is raised.
I have checked each class and noticed that classes are loaded by AppClassLoader and RestartClassLoader.
This bean is registered by @Import configuration class. Spring Framework is registering beans with AppClassLoader but classes of other beans are loaded by RestartClassLoader.

For anyone hitting this issue with Drools, I found this config worked for me:
META-INF/spring-devtools.propertiesIt will happen indeed with any library that deserialize content. Caching libraries, in particular, are affected.
@gaeloberson That should be the right place. Try putting a breakpoint on
DevToolsSettings.isRestartInclude(...)to see if therestartIncludePatternsget loaded and if the regex applies cleanly. If you don’t get anywhere please open a new issue (ideal with a sample project to reproduce the problem).I’ve added support for
META-INF/spring-devtools.propertiesfiles which can be used to pull jars up to the restart classloader. Hopefully you can add arestart.include....regex to solve your issue.
