------------------------------------
Summary: HTL scripts do not compile on Windows if the compiler
needs to generate any warnings
Key: SLING-6445
URL: https://issues.apache.org/jira/browse/SLING-6445
Project: Sling
Issue Type: Bug
Components: Scripting
Affects Versions: Scripting Sightly Engine 1.0.18
Reporter: Vlad Bailescu
Priority: Critical
If an HTL script with potential warnings is compiled on Windows, the compiler
will fail with a NPE like:
{code}
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
at java.lang.String.substring(Unknown Source)

{code}
The compiler assumes that system line separators are being used in the files,
which most of the times is not happening as the scripts might have been edited
on another system.
