Daniel Kulp commented on CXF-7940:
----------------------------------
Just a note: with the removal of this, if there are temp files that are locked
due to streams not being closed properly, they may remain after shutdown. The
purpose of that line was to hopefully get the file streams and such garbage
collected and finalized so that the files can be removed. With this change,
if the delete fails, it will likely just keep the files around. (and this is
really just Windows issue as all the unix's can delete open files)

> Key: CXF-7940
> URL: https://issues.apache.org/jira/browse/CXF-7940
> Project: CXF
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.0.0-milestone1, 3.3.0
> Environment: *OS*: Windows
> *AppServer*: WildFly 10.0.0.1.Final
> *CXF*: cxf-core-3.1.6
> *jbossws-cxf*: jbossws-cxf-server-5.1.5.Final
> Reporter: Viacheslav
> Assignee: Colm O hEigeartaigh
> Priority: Minor
> Fix For: 3.3.0
>
>
> *Brief introduction:*
> We use WildFly server.
> As we know, WildFly based on JBoss Application Server.
> WildFly have an integration with Apache CXF through
> "[jbossws-cxf|https://github.com/jbossws/jbossws-cxf]"; project.
> When WildFly server is stops we see repeated invokes of
> WSDLFilePublisher.java#unpublishWsdlFiles that invoke FileUtils#removeDir
> *Cause of problems:*
> When the method FileUtils#removeDir is invoked then we see the invoke of
> FileUtils#delete:
> https://github.com/apache/cxf/blob/master/core/src/main/java/org/apache/cxf/helpers/FileUtils.java#L254.
> We see some strange code:
> {code:java}
> public static void delete(File f, boolean inShutdown) {
> if (!f.delete()) {
> if (isWindows()) {
> System.gc();
> }
> {code}
> This leads to dramatically slowdown of WildFly server shutdown on Windows
> systems.
> For example, our WildFly server stops in 2781ms without this call AND stops
> in 119882ms with this call (~ 43 times slower).
> *Questions:*
> What is the reason of this code?
> Is it bug? What are the disadvantages of removing this code?
> Last changes of this code from Git Blame:
