Error when reloading Jersey resource

[oranheim]

My deps:

• Undertow 1.2.11
• Weld 2.4.1
• Deltaspike 1.7.2
• Jersey 2.25

I'm getting a NoSuchFieldException exception when I modify a Jersey Resource:

I've push a fix of it. Could you please check it ? Thanks

[oranheim]

Great. Changed log level to debug and found that there is an infinite loop:
