The WLS folks are finding that Derby/JavaDB fails in network mode when launched from a network mounted directory.

This bug is created after the WLS bugdb 18330953 for us to track the Derby 10.11 fix that would need to be included in the next upcoming JUL CPU (8u51).

This is very likely related to https://issues.apache.org/jira/browse/DERBY-6503.
Related issues to keep an eye on:

Workarounds:
WLS reports:
" I found the “java.nio.file.NoSuchFileException” is caused by
$DOMAIN_HOME/common/db isn’t exist, so I add scripts to create
this folder in $DOMAIN_HOME/bin/startWeblogic.cmd can fix the
bug as a workaround, but derby code still need to improve. When
-Dderby.system.home point to a non- exist folder, it should create"

We recommended instead setting the property derby.storage.useDefaultFilePermissions to false, per
http://db.apache.org/derby/docs/10.10/ref/rrefproperdefaultfileperms.html
