Invalid JAVAVM after patch on Oracle ROOH 18.8 (Windows)

Although my main work is as a developer, among other thing I’m also in charge of testing infrastructure (to test my work) and I usually face issues, the below is a problem that occurred on Windows Server 2019
Symptoms, invalid JAVAVM component after patching Oracle DB 18 with 18.8.0.0.191015
RU.
Interim patch 28267731 (WINDOWS OJVM BUNDLE PATCH : 18.3.0.0.180717 (28267731))

This happened on a Read Only Oracle Home configuration

The alert log

fix
Prepare your terminal
set ORACLE_SID=cdb18eero
set ORACLE_HOME=C:\databases\rooh\18x\dbhome_1ee
set PATH=%ORACLE_HOME%\bin;%PATH%
set PATH=%ORACLE_HOME%\OPatch;%ORACLE_HOME%\bin;%PATH%
set PERL5LIB=%ORACLE_HOME%\perl\lib
Having your database in open mode with all the PDBs
sqlplus / as sysdba alter pluggable database all open;
execute the following
%ORACLE_HOME%\perl\bin\perl %ORACLE_HOME%\rdbms\admin\catcon.pl -d %ORACLE_HOME%\javavm\install -b %ORACLE_SID%_javafix update_javavm_db.sql

once it finished, restart the database and open the containers again, then create a file with the below content (I called it c:\temp\fix.sql
)
@?/rdbms/admin/utlrp EXEC DBMS_STATS.GATHER_DICTIONARY_STATS; BEGIN DBMS_STATS.GATHER_FIXED_OBJECTS_STATS; END; / set line 180 set pagesize 50 COL COMP_ID for a10 COL COMP_NAME for a40 COL VERSION for a20 COL VERSION_FULL for a20 COL STATUS for a15 COL SCHEMA for a15 SELECT COMP_ID, COMP_NAME,VERSION,STATUS,SCHEMA,VERSION_FULL FROM SYS.DBA_REGISTRY WHERE STATUS = 'INVALID'; set line 180 set pagesize 50 col OWNER for a11 col OBJECT_NAME for a40 col OBJECT_TYPE for a20 SELECT OWNER, OBJECT_NAME, OBJECT_TYPE FROM SYS.DBA_OBJECTS WHERE STATUS = 'INVALID' order by OBJECT_NAME,OWNER;
and run
%ORACLE_HOME%\perl\bin\perl %ORACLE_HOME%\rdbms\admin\catcon.pl -d c:\temp -b %ORACLE_SID%_fix fix.sql

after that all is perfect
