significantly for applications that print stack traces or make logging calls
frequently.
@item gnu.gcj.runtime.NameFinder.show_raw
Whether the address of a stack frame should be printed when the line
number is unavailable. Setting this to @code{true} will cause the name
of the object and the offset within that object to be printed when no
line number is available. This allows for off-line decoding of
stack traces if necessary debug information is available. The default
is @code{false}, no raw addresses are printed.
@item gnu.gcj.runtime.NameFinder.remove_unknown
Whether stack frames for non-java code should be included in a stack
trace. The default value is @code{true}, stack frames for non-java
code are suppressed. Setting this to @code{false} will cause any
non-java stack frames to be printed in addition to frames for the java
code.
@item gnu.gcj.runtime.VMClassLoader.library_control
This controls how shared libraries are automatically loaded by the
built-in class loader. If this property is set to @samp{full}, a full
