Yes.
Looks like you've already submitted:
https://glassfish.dev.java.net/issues/show_bug.cgi?id=5402
and confirmed that the workaround of setting
<jvm-options>-Dcom.sun.enterprise.server.ss.ASQuickStartup=false</jvm-options>
fixes the issue.
See
https://glassfish.dev.java.net/issues/show_bug.cgi?id=5321
for umbrella issue regarding the need to disable ASQuickStartup in
many scenarios.
