> Recursively deleting tmp directories as part of Bootstrap.bootstrap() prevents multiple embedded server restarts. I believe it has to do with how directories are crated as part of static VFS initialisation.
> TempFileProvider has this static code
> {code}
>     static {
>         String configTmpDir = System.getProperty(JBOSS_TMP_DIR_PROPERTY);
>         if (configTmpDir == null)
>             configTmpDir = System.getProperty(JVM_TMP_DIR_PROPERTY);
>         try {
>             TMP_ROOT = new File(configTmpDir, "vfs");
>             TMP_ROOT.mkdirs();
>         }
>         catch (Exception e) {
>             throw new RuntimeException("Can't set up temp file provider", e);
>         }
>     }
> {code}
> which creates the vfs directory only once that [this patch|https://github.com/jbossas/jboss-as/commit/ad3e878098] removes. As a consequence on server restart with jboss-vfs on the boot classpath hte vfs directory is missing an no tmp file can be created.
> Generally, the server should only remove state on shutdown that it creates itself on startup/run. Alternatively, jboss-vfs should support a start/stop lifecycle in the TempFileProvider and possibly in other entities that also use static initialisers.
