[jira] [Commented] (AXIS2-5303) In case of multiple Axis2
instances, some of them fail during parallel startup, as result of NPE in
TempFileManager
[ https://issues.apache.org/jira/browse/AXIS2-5303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13262517#comment-13262517 ]
Stoyan Tsonev commented on AXIS2-5303:
--------------------------------------
All Axis2 versions using TempFileManager, including trunk, can be affected. But we observe the problem with 1.6.0

> Key: AXIS2-5303
> URL: https://issues.apache.org/jira/browse/AXIS2-5303
> Project: Axis2
> Issue Type: Bug
> Components: kernel
> Affects Versions: 1.6.0
> Environment: AIX 6, WebSphere AS 7.0
> Reporter: Stoyan Tsonev
>
> We are running WebSphere cluster with multiple instances of Axis2.
> During parallel start-up all of them (together) are "trying" to do temp folders clean-up in the static initializer of TempFileManager
> But some instances are "faster", some are "slower" and as result of this time-race "slow" instances can end-up in non-functional state (see the log bellow).
> Solution: A simple check in method "private static void recursiveDelete(File rootDir)" after "File[] files = rootDir.listFiles();"
> if (files != null) { ...}
> should fix the issue.
