Dear GlassFish users I'm trying to upgrade the GlassFish Server Open Source Edition from 3.1.2 to 3.1.2.2 with a side-by-side upgrade path and the help of the asupgrade tool, following the upgrade guide (chapter "To Upgrade From the Command Line Using Upgrade Tool"). Unfortunately the upgrade fails with the following exception: asadmin: SEVERE: Error upgrading config for secure DAS-to-instance admin traffic asadmin: org.jvnet.hk2.component.ComponentException: injection failed on com.sun.enterprise.security.ssl.SSLUtils.secSupp with class com.sun.enterprise.server.pluggable.SecuritySupport [...] asadmin: Caused by: java.io.IOException: Keystore was tampered with, or password was incorrect The old version is located at /opt/glassfish-3.1.2 and symlinked to /opt/glassfish, whereas the new version will be located at /opt/glassfish-3.1.2.2. The old version uses a site specific master password (not the default one). I've used the following steps to upgrade to the new version: cd /var/tmp wget http://download.java.net/glassfish/3.1.2.2/release/glassfish-3.1.2.2.zip mkdir --mode=755 /opt/glassfish-3.1.2.2 unzip glassfish-3.1.2.2.zip -d /opt/glassfish-3.1.2.2 rm -rf /opt/glassfish-3.1.2.2/glassfish3/glassfish/domains/domain1 /opt/glassfish-3.1.2.2/glassfish3/glassfish/bin/asupgrade \ --console \ --source /opt/glassfish/glassfish3/glassfish/domains/domain1 \ --target /opt/glassfish-3.1.2.2/glassfish3/glassfish/domains On the "Enter the master password" prompt I've entered the same master password as on the old version, however asadmin doesn't seems to be able to access the keystore. I've used copy and paste for entering the master password and also verified it on the old version beforehand. Afterwards I've compared the MD5 sums of the following files on both versions, they all match. .../domains/domain1/config/keystore.jks .../domains/domain1/config/cacerts.jks .../domains/domain1/master-password I was also able to list the content of the keystore and the cacerts with help of the keytool and the master password of the old version. Are there any pre-upgrade steps that I've missed or what could be the cause of the above error? Please find attached the complete upgrade log file. Thanks a lot in advance for your help. Christian
