> Due to a java bug "URLClassLoader.getResourceAsStream locks jar files"
> http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5041014
> When you use PackageInstaller.installPackage(installDir, pearFile, true, true); twice from an application because you want to hot-redeploy a new version of a PEAR, you have an error:
> java.io.IOException: Error while trying to clean the installation directory MyPearDir 
> 	at org.apache.uima.pear.tools.InstallationController.extractFilesFromPEARFile(InstallationController.java:742)
> 	at org.apache.uima.pear.tools.InstallationController.extractPEARFile(InstallationController.java:854)
> 	at org.apache.uima.pear.tools.InstallationController.installComponent(InstallationController.java:1551)
> 	at org.apache.uima.pear.tools.PackageInstaller.installPackage(PackageInstaller.java:171)
> A patch is proposed in this article
> http://management-platform.blogspot.com/2009/01/classloaders-keeping-jar-files-open.html
> I have implemented it modifying the UIMAClassLoader and the InstallationTester classes and it works
> I can submit a patch if you find it usefull
