Karel Hübl commented on PIVOT-965:
----------------------------------
I retested other application based on 2.0.4 which is currently running under
JRE 1.7 and found it very unstable under JRE 1.8 - many many errors connected
to replacement of Rhino by Nashorn. The problems are connected not only
tosecurity warnings, but also with usage of mapping functions. Unfortunatelly I
am unable to create simple test case demonstrating all the problems.
To fix it, beside including rhino script engine jars, we also need to change
DEFAULT_LANGUAGE in BXMLSerializer to "rhino". This is not possible in 2.0.4.
To enable it, I had to fork pivot and make change in BXMLSerializer
implementation.
I am including patch from our fork. May be in 2.0.5 it should be possible to
override default language on BXMLSerializer descendants. This can be done by
introducing defaultLanguage protected property (see the patch).
> Java 8 BXML scripting security issues in Apache Pivot RIAs
> ----------------------------------------------------------
>
> Key: PIVOT-965
> URL: https://issues.apache.org/jira/browse/PIVOT-965
> Project: Pivot
> Issue Type: Bug
> Components: core-serialization
> Affects Versions: 2.0.4
> Environment: Windows, Sun JRE 64-bit 1.8.0_31b13
> Reporter: Karel Hübl
> Assignee: Roger Whitcomb
> Labels: java8, jdk8
> Fix For: 2.1, 2.0.5
>
>
> We encounter security issues in our pivot application after upgrading to JRE
> 1.8. The application is deployed as RIA using Java Web Start.
> I found out, that the problem is connected with nashorn script engine which
> replaced rhino script engine from previous java version. BXMLSerializer is
> using ScriptEngine to evaluate scripts in BXML files. It seems, that all
> calls initiated from BXML scripts, are considered untrusted in JRE 1.8 RIA
> Environment - this means security dialogs and exceptions are thrown, when
> trying execute privileged actions (network communication, reflection ...).
> Currently, I am not sure, if this is Pivot or Nashorn bug, but it is problem
> for current Apache Pivot RIAs. To investigate the srcipting behaviour in
> RIAs, I created testing non Pivot project
> https://github.com/kaja78/jnlpScripting The project contains testing
> application, which is deployed as JWS. When you execute the java web start
> app in JRE 1.8, the security dialog is displayed when testing method is
> executed from nashorn script engine (if you press cancel button on security
> dialog, you get SecurityException). When you uncomment 2 lines in
> Webcontent/jnlpScripting.jnlp file, rhino script engine is used instead of
> nashorn and no security dialog is displayed. This fix works also for our
> Pivot RIAs.
> I believe, Pivot should work in JRE 1.8 RIA Environment without security
> issues by default, so it should be fixed somehow in Pivot - may be, by
> correct ScriptEngine configuration in BXMLSerializer or by including Rhino
> libraries in Pivot distribution. Any idea how to "correctly" fix this issue?
> Btw.: I found this bug: http://bugs.java.com/view_bug.do?bug_id=8045075 I am
> not sure, if it is the same problem. But anyway, it should be fixed in
> 1.8.25.b01 and we are encountering above issues in latest 1.8.0.31.b13.
