minimserver start error after update 130

[MN01]

Hi,
I run minimserver on my synology D710+ since years without problems.
But after the last update 130 minimserver stopped with the following error message:

Minimserver start error: java.lang.UnsupportedClassVersionError: com/minimserver/ServerLauncher : Unsupported major.minor version 52.0

Attached you find the minimserver-crash-report and the current versions on my DS710+.

Any ideas?

For a quick fix: Could you provide me an installation package without update 130?

Many thanks
Marc
