[jboss-jira] [JBoss JIRA] (JBVFS-202) Invalid Local file header in ZIP file

[Martin Both (JIRA)]

     [ https://issues.jboss.org/browse/JBVFS-202?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Martin Both updated JBVFS-202:
------------------------------
    Description: 
I'm try to use the Embeddable EJBContainer of JBoss EAP 6.4.
I get a ZipException: invalid CEN header (bad signature)
JBoss writes an invalid Zip- file in
JBossEAP6.4\standalone\data\content\58\a481cdfbe31a8ad823b6708f17151589954ac6/content

The reason is, that the zip file content contains a Local file header with no size for the file data. No Zip-Tool can unzip that and even JBoss cannot read that again.
Compare the method bufferLocalFileHeader() with the method bufferNextCentralFileHeader() of class org.jboss.vfs,VirtualJarFileInputStream.
The one wirtes file sizes the other one not. If you would read the file format specification of zip files than you would know that after the LocallFileHeader the file data is written. Without knowledge of the compressed size it is not possible to read that.

Deployment with Embeddable EJBContainer does not work for me due to this bug.
