Scott Murphy commented on SLING-1511:
-------------------------------------
Also, I am having problems trying to run a script from a java web application
because of the fact the classpath is being built from environment variable
Strings. Is it possible to use the existing ClassLoader? I see this was
discussed here:
http://scala-programming-language.1934581.n4.nabble.com/How-to-compile-Scala-code-from-java-using-the-current-ClassLoader-instead-of-a-string-based-classpat-td1955873.html#a1955873
but no one every replied to it.
The problem I am having is I get a read java.security.AccessControlException
when trying to execute the following code:
new ScriptEngineManager().getEngineByName("scala").eval("println(\"hello\")")
javax.script.ScriptException: Error executing script

Which is obviously happing because of the following code from
ScalaCompiler.scala:
new classPath0.BuildClasspath(settings.classpath.value,
settings.sourcepath.value,
settings.outdir.value, settings.bootclasspath.value,
settings.extdirs.value,
settings.Xcodebase.value, classes)
}
because it is building the classpath from Strings.

> Assignee: Carsten Ziegeler
> Priority: Minor

> As discussed [1] it would be nice if we could decouple the Scala scripting
> engine from Sling making it into a independent JSR 223 compliant script
> engine which is 'just' used by Sling.
