Hi,
Spring Boot released its 2.0.0.RELEASE version just a day after we had released our 7.1.7. version of JRebel. By the time of 7.1.7 release, we were compatible with the 2.0.0.RC2 version of Spring Boot but the 2.0.0.RELEASE version introduced some small nuances that needed correcting – the stack trace you experienced being one of them.
For now, we have solved these integration problems with the Spring Boot 2.0.0.RELEASE version.
Should you wish to give it a go, the fixes are available in the nightly build which can be obtained from the following link:
https://zeroturnaround.com/software/jrebel/download/nightly-build/
If you don’t wish to use a nightly build then this fix will also be included with the next (2018.1.0) release of JRebel. Estimated release date of that version is at the beginning of April.
All the best,
Tiit
