Description

Since Felix 1.4.0, each method invocation is now check in the class SecureAction. When we DON'T set the security manager as argument of the command line and a started bundle tries to set this one, we always get an infinite loop:

at java.net.URL.<init>(URL.java:413)
at sun.security.provider.PolicyFile$3.run(PolicyFile.java:676)
at java.security.AccessController.doPrivileged(Native Method)

at java.net.URL.<init>(URL.java:413)
at sun.security.provider.PolicyFile$3.run(PolicyFile.java:676)

... until a stack overflow.

To reproduce it, just start the attached bundle that does:

System.setSecurityManager(new RMISecurityManager());
URL wantBug = new URL("http://felix.apache.org");
System.out.println("I want a bug: " + wantBug.toExternalForm());

If the security manager is set in the command line, there is no bug.
