HotSwapAgent Wildfly 16

[Alejandro Navalon Fernandez]

Hi all,

I'm trying to use HotSwapAgent with Wildfly 16 and Eclipse Jee 2019-06.

I have already downloaded the OpenJDK Hotswap and add it to my IDE.

When I change a class i get this warning:

WARNING: An illegal reflective access operation has occurred

WARNING: Illegal reflective access by org.hotswap.agent.util.ReflectionHelper (file:/C:/Program%20Files/Java/java%20dcevm-11.0.1+8/lib/hotswap/hotswap-agent.jar) to method com.sun.beans.WeakCache.put(java.lang.Object,java.lang.Object)

WARNING: Please consider reporting this to the maintainers of org.hotswap.agent.util.ReflectionHelper

WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations

WARNING: All illegal access operations will be denied in a future release

But the log shows that the class has been redefined.

When I test if changes has been done I get this error:

#
