Jenkins 1.456, thinBackup 1.6
I installed thinBackup 1.6 on our Jenkins 1.456. I didn't restart the server yet.
In thinBackup's settings page, I get an 'ERROR' below each of 'Backup directory', 'Backup schedule for full backups', 'Backup schedule for differential backups' and 'Files excluded from backup'.
The Stacktrace is as follows:
java.lang.NoSuchMethodError: java/lang/String.isEmpty()Z

Is there something wrong with my configuration?
Thanks.
[JENKINS-13874] java.lang.NoSuchMethodError: java/lang/String.isEmpty()Z

added a comment - I do not want to fix this, because Java5 is very old and not supported anymore by Oracle. So the minimum requirement will be Java 6.
Please reopen it if you have a strong opinion against my decition.

I agree that Java5 is old. But Jenkins is supposed to support this version : https://wiki.jenkins-ci.org/display/JENKINS/Java+5+Compatibility
So I guess its plugins should also support it, no ?
I understand your opinion on the subject. I am sure it is difficult to maintain plugins Jenkins, especially with problems of the JDK version.
Using Java6 is not a problem for me, but I feel that there is a problem of consistency between the versions supported by Jenkins and its plugins.
Maybe you could specify that this plugin is not compatible with Java5 on the wiki ?

String#isEmpty() is available since java 1.6 so you need a JRE 1.6 which runs your jenkins. do you have a JRE 1.6 or greater installed and is this JRE used from jenkins?
