CommandBox/ForgeBox have been updated to run CF 2025-beta.2. Please note: • You MUST be using the latest CommandBox 6.2.0-alpha build to support the new Jakarta EE spec • You MUST update to the latest CFConfig version, which I just published a few minutes ago to support some XML config changes in beta.2 • beta.2 appears to not allow execution of any pre-compiled CFM files now, which means any error page and the entire administrator is unusable by default, lol. You can fix this by running

server set jvm.properties."coldfusion.compiler.block.bytecode"=false

in CommandBox to set the system property that allows those files to run again. Then start the server with

start cfengine=adobe@2025-beta

(which will grab

beta.2

by default.

Is this block byte code thing for real ?

No clue. Thats just what J saw when testing out beta 2. Maybe check the release notes on the prerelease site and see if they mentioned it.
