java.io.SyncFailedException: JBAS016855: copied content does not match expected hash for item: ModuleItem{...}

Environment

• Red Hat JBoss Developer Studio(JBDS) 9.0.0
• Red Enterprise Application Platform (EAP) 6.4

Issue

I'm configuring JBDS 9.0.0GA (jboss-devstudio-9.0.0.GA-CVE-2015-7501-installer-eap.jar) and just tried to patch its EAP to 6.4.5 (jboss-eap-6.4.5-patch.zip)... it fails with this error:

java.io.SyncFailedException: JBAS016855: copied content does not match expected hash for item: ModuleItem{org.apache.commons.collections:main}

• Used jboss-cli.bat with "patch apply D:\path\jboss-eap-6.4.5-patch.zip"
• Same error if I try to patch to 6.4.4
• The patch works SUCCESSFULLY on the older CR1 release jboss-devstudio-9.0.0.CR1-installer-eap.jar
• I applied the patch immediately after installing JBDS, doing a one time start of jbdevstudio.bat

And these lines are printed in the EAP server log:

11:57:11,286 ERROR [org.jboss.as.patching] (management-handler-thread - 5) JBAS016802: failed to undo change for: 'MiscContentItem{bin/client/jboss-cli-client.jar}'

Resolution

• Rollback the one off patch as shown in [1] (use --reset-configuration=false to not change your configuration) and then apply the cumulative patch using the patch command as shown in [2]

• It can be a issue where the files copied from Windows to Unix Machine and it has Ctrl+M characters, which can be confirmed by using cat -v <FILENAME>. If the file has CtrlM characters, that can be handled by using dos2unix /path/to/<FILENAME>.

There is a bug listed in the root cause to fix the issue in a future cumulative patch, so that the rollback is not needed.
