[jira] Created: (UIMA-1652) Cannot hot-install a PEAR twice
Cannot hot-install a PEAR twice
-------------------------------
Key: UIMA-1652
URL: https://issues.apache.org/jira/browse/UIMA-1652
Project: UIMA
Issue Type: Bug
Components: Tools
Affects Versions: 2.2.2
Environment: Windows
Reporter: Olivier Terrier
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

Posted by Thilo Goetz <tw...@gmx.de>.
Just like with the bootstrap loader thingy, this will fail
when run under a security context that doesn't allow futzing
with loaded classes (which, when you think about it, really
shouldn't be allowed anyway). Before we add this, I'd like
to see it tested in applets and application servers to make
sure it does no harm. For the bootstrap loader this doesn't
matter, for the UIMAClassLoader it matters very much. (I
have no idea if UIMA even runs in applets, for that matter).

I guess the question is - should we wait for Java 7 and fix this then,
or patch this now (in the current pending release, for instance)?
Any opinions ?

RE: [jira] Commented: (UIMA-1652) Cannot hot-install a PEAR twice
Posted by Olivier Terrier <ol...@temis.com>.
I tested the code on SUN's Java6 JRE
On other JVMs (IBM) the code should just do nothing and return (-> bug not fixed but same behavior as before) but I didn't test it
