Chapman Flack commented on MNG-6275:
------------------------------------
Hi,
By following a link from the maven-antrun-plugin, I am under the impression
that this issue might be the underlying reason I am seeing this error with a
build that includes a <script> in an <antrun>:
{code}
Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run
(pg_config to pgsql.properties) on project pljava-so: An Ant BuildException has
occured: Unable to create javax script engine for javascript
{code}
Does that sound right? If so, what's the outlook for a resolution?
Thanks!

> Project: Maven
> Issue Type: Bug
> Components: Class Loading
> Reporter: Robert Scholte
> Assignee: Stephen Connolly
> Priority: Critical
> Fix For: 3.x / Backlog

>
> Spotted this issue via MANTRUN-200. The reason is that in the
> {{DefaultClassRealmManager}} a new realm is created where the parent
> classLoader is {{null}}. This implies that the bootstrap classloader is used
> as parent.
> With Java8 nashorn has become an extension and is not part of the bootstrap
> classloader anymore.
> It is kind of strange that we want the bootstrap classloader here, it makes
> more sense if the system classloader is used (but with Java 7 and older
> versions of Java this was not an issue, both worked fine).
