[jboss-jira] [JBoss JIRA] (WFLY-166) Clearing server environment in bootstrap breaks embedded server restart

Clearing server environment in bootstrap breaks embedded server restart ----------------------------------------------------------------------- Key: WFLY-166 URL: https://issues.jboss.org/browse/WFLY-166 Project: WildFly Issue Type: Bug Components: Server Reporter: Thomas Diesler Assignee: Bartosz Baranowski Fix For: 8.0.0.CR1 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.
