Enable general security policy debugging
14.2. Debugging Security Policy Issues You can enable debugging information to help you troubleshoot security policy-related issues. The java.security.debug option configures the level of security-related information reported. The command java -Djava.security.debug=help will produce help output with the full range of debugging options. Setting the debug level to all is useful when troubleshooting a security-related failure whose cause is completely unknown, but for general use it will produce too much information. A sensible general default is access:failure . Procedure 14.2. Enable general debugging This procedure will enable a sensible general level of security-related debug information. Add the following line to the file run.conf (Linux), or run.conf.bat (Windows): Linux JAVA_OPTS="$JAVA_OPTS -Djava.security.debug=access:failure" Windows JAVA_OPTS="%JAVA_OPTS% -Djava.security.debug=access:failure"
