[jira] [Commented] (VELOCITY-984) Velocity calls method of abstract superclass leading to an IllegalAccessException

    [ https://issues.apache.org/jira/browse/VELOCITY-984?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17887790#comment-17887790 ] 

Thomas Mortagne commented on VELOCITY-984:
------------------------------------------

bq.  throw/catch mechanisms are slow

Yes, it's definitely not great. Any thought on moving Velocity to Java 11 ? 😇

bq. resort to Java 9+ canAccess() when possible

You mean using reflection to check if Method#canAcess exist and call it in that case ? I guess that should not be too hard indeed, I will try that quickly.

> With the changes introduced in VELOCITY-952, our templates fail with an IllegalAccessException.
> The exception is caused by a template that has a variable of type StringBuilder and calls append on it. The introduced changes choose the implementation of the method of AbstractStringBuilder to be executed, which leads to the mentioned IllegalAccessExceptions.
> I've attached an extended version of Velocity952TestCase.java that reproduces the problem with an additional test.
