[jira] [Created] (SLING-7291) HTL to Java compilation might fail under heavy load

Radu Cotescu created SLING-7291:
-----------------------------------

             Summary: HTL to Java compilation might fail under heavy load
                 Key: SLING-7291
                 URL: https://issues.apache.org/jira/browse/SLING-7291
             Project: Sling
          Issue Type: Bug
          Components: Scripting
    Affects Versions: Scripting HTL Engine 1.0.20
            Reporter: Radu Cotescu
            Assignee: Radu Cotescu
            Priority: Minor
             Fix For: Scripting HTL Engine 1.0.46


When there's a high number of concurrent threads accessing the same HTL script that needs to be compiled, compilation might fail since these threads try to write to the same file-system based file.

In the end the script will be compiled correctly since the HTL engine will retry the operation until a valid Java class is generated, however this should be avoided with a simple locking mechanism.
