Hi,

I am trying to start our wildfly 32 server with openJDK 25, it fails immediately wih following stacktrace:

May be java 25 is not supported by wildfly 32 ?

Thanks in advance.

Release announcement of WildFly 32 [1] says Java 21 is recommended, 11
and 17 also supported. WildFly 38 announcement says the following.

So the latest release does work with Java 25, but it is still not the
recommended version.
