Can be utilized anywhere within the command line, together with within an argument file, to stop further more @filename expansion. This option stops increasing @argfiles following the choice.
The option can be utilized in testing to simulate a long-operating method with all virtual memory mapped to Actual physical memory. By default, this selection is disabled and all webpages are dedicated as JVM heap Place fills.
File names in an argument file are relative to The existing Listing, to not the location of the argument file.
You employ large pages, also called large web pages, as memory web pages which are drastically much larger compared to common memory page measurement (which varies according to the processor and functioning system). Massive web pages improve processor Translation-Lookaside Buffers.

An open up quotation stops at conclusion-of-line Except is link the last character, which then joins the subsequent line by eradicating all top white space characters.

Windows: The following instance demonstrates how the -XX:OnError choice can be used to run the userdump.exe utility to get a crash dump in case of an irrecoverable mistake (the %p designates The present procedure).
Sets the Original code cache measurement (in bytes). Append the letter k or K to indicate kilobytes, m or M to click for info indicate megabytes, or g or G to indicate gigabytes.
Sets a tailor made command or maybe a series of semicolon-separated commands to run when an irrecoverable error occurs. Should the string includes Areas, then it must be enclosed in quotation marks.
