Problems with lib jetbrains and Java 7

[tfinez]

Plugin jetbrains is not compatible with a system running Java 7. We have the version 2013 sp1 then we can't update to Java 8, because we will lost the support from sdl Tridion if we have any issue. Please keep compatible with both products: 2013 sp1 and web8. The master version is not working with java 7.

[bkoopman]

Can you provide a bit more detail on where you encounter this issue exactly? Please also note that for 2013 SP1, Java 8 is the advised prerequisite as documented http://docs.sdl.com/LiveContent/content/en-US/SDL%20Tridion%20full%20documentation-v1/GUID-DBBDB18C-93AC-4E8E-B529-A9321E706C9A

Java 7 is only required when using an IBM DB2 broker database.

When trying to start the app with JBoss EAP + jdk 1.7, we get the following error:

java.lang.UnsupportedClassVersionError: org/jetbrains/annotations/Nullable : Unsupported major.minor version 52.0

When it's trying to load the beans in the classes that are using this lib.

I add the full stacktrace error:

dxa-common-impl-1.6.0-SNAPSHOT.jar/com/sdl/webapp/common/impl/contextengine/DeviceFamiliesEvaluator.class"; nested exception is java.lang.UnsupportedClassVersionError: org/jetbrains/annotations/Nullable : Unsupported major.minor version 52.0

Thank you Bart. Then we will have to use the version 13.0 which is compatible until we migrate to java 8.

[bkoopman]

Please note you are using the unreleased 1.6 snapshot versions there, you might want to stick with the release/1.5 branch since you won't have the CM version of 1.6 until that is released.

[NunoLinhares]

we can't update to Java 8, because we will lost the support from sdl Tridion

This is not true. It was announced in the support newsletter and the documentation was updated - we support Java 8 on SDL Tridion 2013 SP1 (both CM and CD) with no code changes. See http://docs.sdl.com/LiveContent/content/en-US/SDL%20Tridion%20full%20documentation-v1/GUID-DBBDB18C-93AC-4E8E-B529-A9321E706C9A for more info.

Also we compile our framework against Java 1.7 for compatibility reasons, as you can see in https://github.com/sdl/dxa-web-application-java/blob/master/dxa-framework/pom.xml when building we use 1.7

[tfinez]

We don't have any compilation issue, but runtime issue.
