[sergey-morenets]

Expected Behavior

Micronaut 3 migration should complete without errors

Actual Behaviour

Micronaut 3 migration fails with exception:

[ERROR] Failed to execute goal org.openrewrite.maven:rewrite-maven-plugin:4.12.0:dryRun (default-cli) on project demo: Execution default-cli of goal org.openrewrite.maven:rewrite-maven-plugin:4.12.0:dryRun failed: An API incompatibility was encountered while executing org.openrewrite.maven:rewrite-maven-plugin:4.12.0:dryRun: java.lang.IllegalAccessError: superclass access check failed: class org.openrewrite.java.Java11Parser$ByteArrayCapableJavacFileManager (in unnamed module @0x76cdafa3) cannot access class com.sun.tools.javac.file.JavacFileManager (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.file to unnamed module @0x76cdafa3

@sergey-morenets see the additional commandline args for JDK 16 at openrewrite/rewrite#909. I'll update our docs to include this info

Hi @burtbeckwith

Thank you for the hint. Migration works if I update MAVEN_OPTS environmental variable.
