Sharing Conversations On Mailing Lists

Christian Schlichtherle — Mon, 16 Jan 2012 18:16:34 +0000

It happens every now and then that I get a personal email asking for support on an issue with TrueZIP. Well, this is certainly OK, but I prefer such conversation to happen on the public user mailing list for the benefit of TrueZIP’s small but growing community. Besides, sharing our conversation with others is a way of saying thank you for a free (as in beer) VFS library/framework.

So if you haven’t done already, please subscribe to a TrueZIP mailing list at http://truezip.java.net/mail-lists.html. The most appropriate list is the users list. The announce list should only be used if your interest is solely in announcements – they will get copied to the user list anyway.

If you have a login on http://home.java.net, your subscription should get confirmed instantly. Otherwise I’ll have to do it manually, so please bear with me.

Thanks in advance!

How To Make Comprehensible Stack Traces with Decorator Chains

When getting an exception, it’s often vital to understand the context of the issue by reading the stack trace. However, with foreign code and certain design patterns it’s often hard to comprehend it. Here’s why and what you can do about it in your own code [...more]

TrueZIP 7.4.3 released

Christian Schlichtherle — Wed, 14 Dec 2011 22:30:20 +0000

Just one day after the release of TrueZIP 7.4.2, I was notified about a very unfortunate ZIP64 issue: If an entry >= 4GB size is written to a ZIP file, then this ZIP file will not be readable again by the classes de.schlichtherle.truezip.zip.ZipFile and relatives (including java.util.zip.ZipFile in JSE 7)!

This issue affects the versions 7.3 up to 7.4.2 of the module TrueZIP Driver ZIP. Fortunately, you can easily recover all entries of such a damaged ZIP file using java.util.zip.ZipInputStream in JSE 7 (JSE 6 does not support ZIP64 extensions) or various command line tools, including the jar utility (Windows, Solaris) in JDK 7 or some third party tools.

The reason why this issue could slip through my test suite is that round-tripping ZIP files > 4GB is way too slow to be practical in an automated test suite and so an automated test for such a big ZIP files does not exist. Hence I have manually tested this issue and fixed it.

Everybody please update the dependencies in your POM or download TrueZIP 7.4.3 from the Maven Central Search Site!

My heartiest apologies to anyone affected.

I have updated the archetype for JavaFX 2.0 applications in Scala to version 0.4 in order to reflect the release of JavaFX 2.0. Note that the environment variable JAVAFX_HOME must now refer to the base installation directory of the JavaFX 2.0 SDK, not the subdirectory bin anymore. Here are the updated Maven coordinates for the archetype:
