----------------------------------------

             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.)
