[jira] [Commented] (TOMEE-2619) Eliminate "Can not attach to
current VM" exception
[ https://issues.apache.org/jira/browse/TOMEE-2619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16907874#comment-16907874 ]
Jean-Louis MONTEIRO commented on TOMEE-2619:
--------------------------------------------
Looks like from Java 9 on, Oracle decided a JVM agent cannot attach itself to the current JVM.
There is a flag users can set to enable it.
ByteBuddy forks a process to attach itself to the JVM from another JVM.
See some discussion here [https://github.com/raphw/byte-buddy/issues/295]

> Several examples experience issues getting the openejb-javaagent installed. To reproduce run the example
> * examples/application-composer/
> The example will pass, but it does print out the following output which is not acceptable for a Final release. If there is a known issue, we need a clearer error message and some documentation.
