Problem upgrading to 7.10.0

radius69 · November 30, 2018, 4:24pm

Tried to upgrade from 7.8.0-ee to 7.10.0-ee today.
Environment:

Wildfly 8.2.1.Final in standalone mode
java version “1.7.0_71”
Java™ SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot™ 64-Bit Server VM (build 24.71-b01, mixed mode)
camunda deployed as server-module

According to the docs, 7.10.0 still supports java 7 and wildfly 8.
But on server start, i get the following exception when the module is loaded:
java.lang.UnsupportedClassVersionError: org/camunda/bpm/container/impl/jboss/extension/BpmPlatformExtension : Unsupported major.minor version 52.0

Any hints? Thx.

Hi,

Did you followed the update procedure described here:

And more specifically:

if you are a WildFly 8 user, please download the Camunda WildFly 8 Modules archive for updating the Camunda BPM Modules.

Hi Yana,
thanks, i haven’t seen that!

But why don’t you offer the module as jar-Type in your Repo, just zip-Type?
(see attached screenshot)

Thx
Michael

Hi Michael,

It is zip because you have to unpack it in modules dir.
We usually provide the zip/tar packaging (not jar).

Best regards,
Yana

Hi Yana,
you provided jar-Type in previous releases and in 7.10.0 for wildfly >8 (see camunda-wildfly-modules). So why not for camunda-wildfly8-modules?

Otherwise we have to change our build-process, because we have a dependency on the module.

Thx
Michael

updated our project to use zip-type now for camunda-wildfly8-modules.
everything seems to work now.
thx

I am happy to hear that.
Yes, we provided in 7.10.0-alphaX jar files but we were not finished the adjustments for wildfly distros at that point.
