-------------------------
Summary: Program crashes when StackOverFlow Exception happens from
pulling a softlinked directory that link to the directory that has the same
name one level above
Key: VFS-437
URL: https://issues.apache.org/jira/browse/VFS-437
Project: Commons VFS
Issue Type: Bug
Affects Versions: 2.0
Environment: java version "1.7.0_02"
Java(TM) SE Runtime Environment (build 1.7.0_02-b13)
Java HotSpot(TM) 64-Bit Server VM (build 22.0-b10, mixed mode)
Linux version 2.6.18-238.el5 ([email protected]) (gcc version
4.1.2 20080704 (Red Hat 4.1.2-48)) #1 SMP Thu Jan 13 15:51:15 EST 2011
Reporter: Jason
Priority: Blocker
Fix For: 2.1
With the setting below, StackOverFlow exceptions occur and server crashes
Attept to pull with:
ftp://root:password@ip:/Vol1
Vol directory has the following info
lrwxrwxrwx 1 root root 5 Oct 5 2007 Vol1 -> /Vol1
set the builder.setUserDirlsRoot (opt, true)
When it tries to look for the parent of the Vol1, it goes back to the same
Vol1, which causes a infinite loop that eventually creates stackoverflow
exception.
Exception is shown below
java.lang.StackOverflowError
