Debugging Java Security
When working with java.security packages it is handy to have a tool that would switch on some debugging information about stuff going on inside. Helpfully security classes already contain such debugging calls.
These calls can be enabled via setting -Djava.security.debug=option(,option) system property.
Options can be listed using sun.security.util.Debug.Help() static method call, that prints all the available options to the std.err stream.
The available options are listed in the table.
