----------------------------------------
Summary: Constants check for JRE bitness causes SecurityException
under WebStart
Key: LUCENE-7135
URL: https://issues.apache.org/jira/browse/LUCENE-7135
Project: Lucene - Core
Issue Type: Bug
Components: core/other
Affects Versions: 5.5
Environment: OS X 10.11.4, Java 1.8.0_77-b03 (under WebStart)
Reporter: Aaron Madlon-Kay
I have an app that I deploy via WebStart that uses Lucene 5.2.1 (we are locked
to 5.2.1 because that's what [LanguageTool|https://languagetool.org/] uses).
When running under the WebStart security manager, there are two locations where
exceptions are thrown and prevent pretty much all Lucene classes from
initializing.
# In {{RamUsageEstimator}}, fixed by LUCENE-6923
# In {{Constants}}, caused by the call
{{System.getProperty("sun.arch.data.model")}} (stack trace below).

The latter is still present in the latest version. My patch illustrates one
solution that appears to be working for us.
(This patch, together with a backport of the fix to LUCENE-6923, seems to fix
the issue for our purposes.)
