Upgrade to 6.10 breaks icedtea.
Posted: 2018/07/12 18:37:52
I recently updated several CentOS 6 machines to 6.10. Something in that upgrade seems to have broken iced-tea. It stops with following error message:
AFAIK the "Unsupported major.minor version" is casued by a mismatch between the java version the program expects and the system provides. I have tried to run it with java-1.7.0-openjdk and java-1.8.0-openjdk as well the "official" versions of both 7 and 8 from Oracle. All of them give me the same error.
This doesn't affect any of the servers but there are still a few CentOS 6 workstations that do need icedtea.
Code: Select all
