Karate mock-server fails to load proper contextClassLoader when watch is set to true

[alexjaravete]

I want to use karate mock with a custom library that I created. If I run karate mock without the watch feature it works without any issues. When I enable it, it can sometimes happen that the ContextClassLoader in Suite.java is null. It does not always happen, but only when I start the changing the feature file. And even then it does not happen on every refresh but only on some.

karate/karate-core/src/main/java/com/intuit/karate/Suite.java

Line 142 in fed432f

classLoader = Thread.currentThread().getContextClassLoader();

You can try to reproduce it by creating a MockServer in a Java project and set watch to true. Then add a debug point with a null check in Suite when the classloader is set. Now keep changing something in the feature file and keep making calls to the mock server.

Could we add a check if the ContextClassLoader is null and then call the getClass().getClassLoader()if it's null?
Thanks!
