Messages tagged with gc, meta, andclass aren’t be logged asclass* is ready to off. The default configuration for all other messages at degree warning is in effect aside from Those people which include class.
-XX:SharedArchiveConfigFile=shared_config_file The choice is accustomed to specify added shared facts extra to the archive file. In JDK 9, it supports strings and symbols. The string knowledge and symbol details ought to be created with the jcmd Software attaching to your functioning JVM approach. See jcmd.
.., the change permits assertions in the required bundle and any subpackages. If your argument is just ..., then the switch permits assertions from the unnamed offer in The present Operating directory. With the classname argument, the switch enables assertions in the specified class.
Applies various arguments during the order that they appear about the command line. Numerous -Xlog arguments for the same output override each other in their given order.
The defaults for both of these solutions are 70% and forty% respectively. Simply because functionality sacrifices can take place when working with these tiny settings, it is best to improve for a little footprint by minimizing these settings as much as you possibly can with out introducing unacceptable general performance degradation.
print java/lang/String toString If you’re using commands to the JIT compiler to complete on strategies, then see the -XX:CompileCommand selection.
Enables the choice to stop the java discover this info here command from operating a Java application if any of such directories exists and is not empty:
Linux only: Enables the usage of significant internet pages which can dynamically mature or shrink. This selection is disabled by default. You could face functionality issues with transparent substantial internet pages as the OS moves other pages about to produce substantial pages; this option is built obtainable for experimentation.
String objects which have been promoted to an old heap location before this age has long been achieved are always considered candidates for deduplication. The default price for this option is three. See the -XX:+UseStringDeduplication click to find out more possibility.
It ought to be utilised only on equipment with many sockets, wherever it improves the performance of Java programs that rely upon concurrent functions. Just the Java HotSpot Server VM supports this selection.
Specifies a number of argument information prefixed by @ used by the java command. It isn’t unheard of with the java command line being go right here extremely long due to .jar data files desired from the classpath. The @argument information solution overcomes command-line length limitations by enabling the launcher to grow the contents of argument documents soon after shell expansion, but in advance of argument processing.
Enabled automatic adjustment of your incremental manner obligation cycle according to figures gathered when the JVM was functioning.
Permits strict course-file format checks that enforce shut conformance to The category-file format specification. Builders should really use this flag when producing new code. Stricter checks may perhaps turn out to be the default in upcoming releases.
For the reason that our application will be a "basic outdated Java software", we don't have to have any added technologies to generally be supported. So, Really don't choose any of the choices below Supplemental Libraries and Frameworks.
