[jboss-jira] [JBoss JIRA] (DROOLS-1534) Facing issue with Drools 6.3.0 version while updating to tomcat(Specific to Window platform)

[Mario Fusco (JIRA)]

Mario Fusco resolved DROOLS-1534.
---------------------------------
    Resolution: Rejected


Drools 6.3 depends on ecj 4.3.1. More recent versions (6.5) require at least ecj 4.4.2 to fully support Java 8 syntax. 

Ecj 3.12.1 that you claim is in use by your version of Tomcat seems to be pretty old. To be honest I don't know how and why oldest releases of Tomcat worked regardless of this problem. However this is not a drools issue and unfortunately I'm not aware of any workaround to fix this other than trying to force Tomcat to run with a different (more recent) ecj release.

> Hi Team,
> we upgrade our tomcat as daily update process, previously we are using tomcat 8.5.5 and now updated to 8.5.13, we found that after updating tomcat to 8.5.13 our drools rule are not working and attached the exception for your reference. 
> We analyse the issue and found that *ecj.jar* is causing the issue, please let me know if there is any dependency with ECJ.jar, we are using 3.12.1.v20160829-0950 and it is bundled with tomcat 8.5.13.
> Please let me know if you have any workaround for this issue.
