Subject [jira] Updated: (DERBY-1273) Sysinfo should print a better message when it gets Security Exceptions accessing classpath info when run under security manager
Date Fri, 05 May 2006 00:53:17 GMT
     [ http://issues.apache.org/jira/browse/DERBY-1273?page=all ]

Andrew McIntyre updated DERBY-1273:
-----------------------------------

    Attachment: DERBY-1273.diff

Attaching a patch that gets rid of the getProtectionDomain exception in the above output.
If we can access the DB2Driver or DB2Version classes from JCC to get the version, then we
can use Class.getResource() to determine the location of the class. If we can't access the
class, we don't print anything.

> If sysinfo does not have getProtectionDomain privileges it cannot get some information
during classpath handling.  
> When this occurs it prints   Java Security Exceptions in the output e.g.
> JRE - JDBC: J2SE 1.4.2 - JDBC 3.0

> [Java Security Exception: access denied (java.io.FilePermission c:\bryan\src\derby\main\trunk\tools\java\jakarta-oro-2.0.8.jar
read)] 
> [Java Security Exception: access denied (java.io.FilePermission c:\bryan\src\derby\main\trunk\tools\java\junit.jar
read)] 
> See DERBY-1229 notes.html for a complete explanation of the output.
> I am actually not sure what information is actually missing from sysinfo in this case
but  I  think it would be better if sysinfo just printed the classpath  and then printed a
generic warning with the information that it was not able to report rather than printing the
Security exceptions explicitly.
> This would be especially helpful for NetworkServerControl sysinfo because users are always
encouraged to run network server in security manager.
