[jira] [Commented] (SLING-6328) JSP concurrent compiling issue

["Julian Sedding (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-6328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15804944#comment-15804944 ] 

Julian Sedding commented on SLING-6328:
---------------------------------------

I did some research on this issue. For the record: it seems Sling JSP is a fork of Jasper 6.0.14 (as indicated by other dependencies of the module with the same version).

The commit to fix the above mentioned [bugzilla issue #45691|https://bz.apache.org/bugzilla/show_bug.cgi?id=45691] is [r707745|http://svn.apache.org/r707745], which was first released with Jasper 6.0.19 and should thus be fairly close to our fork.

>             Project: Sling
>          Issue Type: Bug
>          Components: Scripting
>    Affects Versions: Scripting JSP 2.1.6
>            Reporter: Sameer Charles
>            Priority: Critical
>
> At times JSP fails to compile due to duplicate variable error (Duplicate local variable _jspx_temp0).
> This is suppose to be fixed in jasper (within Tomcat) but not in Sling impl. 
> See https://bz.apache.org/bugzilla/show_bug.cgi?id=45691
> This seems to be the culprit (see line 623) but there might be other issues.
