The Jetbrains JDK releases are unofficial but they provide JREs patched with the DCEVM. They are available at https://github.com/JetBrains/JetBrainsRuntime/releases . These instructions were tested with Release 17_0_13-b164.4, architecture osx-x64, JBR with JCEF (DCEVM), jbr  and jbrsdk. They should also work with architecture osx-aarch64.

Troubleshooting

a. Some versions of macOS may prevent this java from running because of security quarantining. Try removing quarantine from java folder.

sudo xattr -r -d com.apple.quarantine /Library/Java/JavaVirtualMachines/jbrsdk_dcevmjcef-17_0_1-osx-x64-b164.4.0.3-x64-b469

b. In the "Project" menu, "Build Automatically" should be selected for hot swap to work.
