> 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
> Attachments: LUCENE-7135.diff

> 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).
> {code}

> 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.)
