Advanced project options list miscellaneous project specific options that aren't commonly used but are available to you if you ever have the need to configure these advanced options.
Debug with HotSpot
If this option is checked and the HotSpot runtime is available for the Java runtime you have selected to use, your process will be debugged using the HotSpot JVM (the -hotspot JVM option flag is implicitly supplied). While HotSpot running normally is quite fast, when HotSpot is run in debug mode as is required it is much slower than debugging under the classic JVM because HotSpot basically has to revert back to running your program in interpreted mode in order to retain the necessary debug information for you to inspect. Furthermore, when debugging with HotSpot certain features are not available such as field watchpoints, viewing object monitors, and obtaining thread status information because of limitations with the HotSpot engine running in debug mode. Enable this option only if you must.
Launch Paused
When checked, the debug session will initially be paused whenever processes to be debugged are launched from within BugSeeker. You will be required you to select Debug | Continue in order to resume process execution. This setting has no effect if you are debugging remotely as the command to specify that remote session start paused is controlled by the JPDA JVM options you supplied to the remote process when it was started.
JVM Quote Char
Allows you to customize the quote character to use when you are specifying JVM and main class arguments that contain spaces and you wish to treat them as a single argument by surrounding the argument with this quote character. The double quote (") character is the default quote character. Usually, you would need to change the quote character only if you wish to supply the double quote character as one of the arguments to your main class of to the JVM.
