Stuart Rose created LUCENE-4205:
-----------------------------------
Summary: 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
Environment: unsigned applet
Reporter: Stuart Rose
Priority: Minor
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...
