Assignee: Alasdair Nottingham
> Unable to delete EBA file if the value of defaultUseCaches is set to false on
> JarURLConnection on a separate thread during installation

> Key: ARIES-804
> URL: https://issues.apache.org/jira/browse/ARIES-804
> Project: Aries
> Issue Type: Bug
> Components: Application
> Affects Versions: parent-0.4.0
> Environment: Windows 7
> Reporter: Iain Duncan
> Assignee: Alasdair Nottingham
> Attachments: JarLockingInApp804.patch

>
> If you install an EBA into Aries but at the same time a different thread that
> sets the value of defaultUseCaches to false then the EBA cannot be deleted on
> Windows.
> I think this is related to the fix to #ARIES-292. Here after installing the
> application it runs through getting the JAR file for the EBA and closing the
> file. If the use caches is set to true at this point then it will get the
> same JAR file that was used earlier in the installation process and close it.
> However, if use caches is set to false it will create a new JAR file and
> close that thus leaving the one that was opened during the installation open.
> There is a timing element to this because if default use caches is false
> throughout then it won't keep a handle open to the file in the first place
> and if it is true throughout then the fix to 292 works. It is only when the
> value changes from true to false on a separate thread between the
> installation of the EBA and the tidy up that was added for 292.
> I think this will have a simple fix by adding:
> urlc.setUseCaches(true);
> before getting the JAR file in AriesApplicationManagerImpl.install()
