KahaStore is unable to create lock file when user.dir is manually changed
-------------------------------------------------------------------------
Key: AMQ-1883
URL: https://issues.apache.org/activemq/browse/AMQ-1883
Project: ActiveMQ
Issue Type: Bug
Components: Message Store
Affects Versions: 5.1.0
Environment: WinNTFileSystem
jdk 1.6_05
Reporter: Tuomas Kiviaho
I've been getting the following exception
Caused by: java.io.FileNotFoundException:
activemq-data\localhost-kahastore\lock (The system cannot find the path
specified)
at java.io.RandomAccessFile.open(Native Method)
at java.io.RandomAccessFile.<init>(RandomAccessFile.java:212)
at
org.apache.activemq.kaha.impl.KahaStore.initialize(KahaStore.java:476)
I assume that changeset 661435
<http://fisheye6.atlassian.com/changelog/activemq?cs=661435> was aimed to fix
the problem following problem:
Error in directory.mkdirs is masked and can result in FileNotFoundException
when creating tmp_storage directory <http://open.iona.com/issues/browse/MB-360>
I verified that there is no problem in creating the parent directories, but
filesystem thinks that directory doesn't exists after it has been created
succesfully. After little more digging I stumbled upon the following:
File.getAbsolutePath() is incorrect if "user.dir" is set on the command line
<http://bugs.sun.com/bugdatabase/view_bug.do;:YfiG?bug_id=4117557>
There is some more information about using canonical form at Mule project
<http://mule.mulesource.org/jira/browse/MULE-1112> and I found out that using
getCanonicalFile() does indeed work.
As a patch I suggest that all file/directory related methods at IOHelper would
return (canonical) File instead of String.
Other not so intrusive possibility would be to change XBeanBrokerService.
