Hello Pranay, Hopefully, you are doing well. I have seen your email in my Mobile and then somehow missed to acknowledge your email.
Thanks for digging into this - you've got it exactly right on both points. DCEVM coverage: Yes, JBR's built-in enhanced class redefinition is what ofbizDev actually relies on. You're correct that dcevm/dcevm tops out at 8 and TravaOpenJDK at 11 - neither covers trunk's Java 17 baseline (or 21). JBR is the only maintained path that does, officially through 17/21/25. Good catch that the README doesn't say this - right now it just describes JBR as "bundled with IntelliJ," which reads like an incidental detail rather than the reason it's the recommended source. I'll update it to call that out explicitly, so it's clear this isn't leaning on an unmaintained community patch. IDE-agnostic: Also correct. The plugin only ever resolves DCEVM_HOME/-PdcevmHome down to a java executable — there's no IntelliJ dependency in the code at all. Anyone can pull JBR standalone from JetBrains' releases page and point at it, IntelliJ never has to be installed. I'll add a short VSCode-oriented example to the README (grab standalone JBR, set DCEVM_HOME/-PdcevmHome to it, optionally point the Java extension's configured JDK at the same install) so it doesn't read as JetBrains-IDE-only.
