-------------------------------------
This is ram usage estimator. I guess the question is do we support running with
security manager on?
> Constants.java generates AccessControl Exception in unsigned applet
> --------------------------------------------------------------------
>
> Key: LUCENE-4205
> URL: https://issues.apache.org/jira/browse/LUCENE-4205
> Project: Lucene - Java
> Issue Type: Bug
> Components: core/index
> Affects Versions: 3.5, 3.6, 4.0
> Environment: unsigned applet
> Reporter: Stuart Rose
> Priority: Minor
> Labels: applet, unsigned
>
> Using Lucene (i.e. writing a Document to a RAMDirectory) in an unsigned
> applet causes an AccessControlException because Constants.java is attempting
> to read a System property that is not allowed.
> Caused by: java.security.AccessControlException: access denied
> ("java.util.PropertyPermission" "sun.arch.data.model" "read")
> at java.security.AccessControlContext.checkPermission(Unknown Source)
> at java.security.AccessController.checkPermission(Unknown Source)
> at java.lang.SecurityManager.checkPermission(Unknown Source)
> at java.lang.SecurityManager.checkPropertyAccess(Unknown Source)
> at java.lang.System.getProperty(Unknown Source)
> at org.apache.lucene.util.Constants.<clinit>(Constants.java:84)
> on line 84: final String x = System.getProperty("sun.arch.data.model");
> We have tested setting the String x to the property value for "java.vm.name"
> and find that works for us...
