Error [A18115] & [A12258] at Arbortext startup

Hello, 

After upgrading Arbortext editor to 6.0 to 8.1.1 we've got 2 errors : 

- [A18115] Error in initialisation file : D:\Products\Arbortext\8.1.1\adapters\com.ptc.prowt.arbortext\init\dms_customize.acl
- [A12258] Require : couldn't open any package file in the load path

For information, the JRE version is : Adopt OpenJDK 11 and the JAVA custom code is well compiled with this JRE version. 

I've searched in the support topic but cannot find anything related to our issue. 

Do you know how to handle these errors ?

Thanks in advance,
