Jonas Wolf commented on TOMEE-2260:
-----------------------------------

We are trying to upgrade our existing stack TomEE+ 1.7.4/Java 8 to TomEE+ 7.1.0/Java 11. When starting the app, we run into the following error:

As far as I can see, this is because asm6 is not compatible with Java 11.

When will TomEE fully support Java 11?

>          Issue Type: Dependency upgrade
>          Components: TomEE Core Server
>    Affects Versions: 7.0.5, 7.1.0, 8.0.0-M1
>         Environment: Java 11
>            Reporter: Artur Linhart
>            Priority: Major

> Because the TomEE server uses for the analysis of the deployed classes the asm library, there should be included the library asm7, which does officially support all of the features from java 11. It is especially important because Java 11 is the LTS Version from Oracle, so very much suitable for the development of production stable applications. Todays asm6 library used in versions 7.1.0 and 8.0.0-M1 does not support java 11 officially and fully, asm6 in versions 6.2 and 6.2.1 (in xbeans 4.9 and 4.10) supports java 11 only in experimental way.
