You can explicitly set the heap dump file route and name utilizing the -XX:HeapDumpPath option. By default, this selection is disabled as well as heap isn’t dumped when an OutOfMemoryError exception is thrown.

The -enableassertions (-ea) solution applies to all class loaders and to technique lessons (which don’t have a category loader). There’s one particular exception to this rule: If the option is provided with no arguments, then it doesn’t use to program courses. This makes it very easy to permit assertions in all classes apart from technique courses. The -enablesystemassertions selection provides a separate change to allow assertions in all technique courses.

When the command prints practically nothing, then your system doesn’t assistance significant webpages. To configure the procedure to use massive page memory, login as root, and after that observe these measures:

Sets the maximum level of native memory that could be allotted for course metadata. By default, the dimensions isn’t restricted. The amount of metadata for an software depends on the applying by itself, other running purposes, and the level of memory readily available to the system.

Sets the utmost code dimension (in bytes) for compiled methods that should be inlined. Append the letter k or K to point kilobytes, m or M to point megabytes, or g or G to indicate gigabytes.

Allows logging of compilation activity to some file named hotspot.log in the current Performing directory. It is possible to specify a distinct log file path and identify using the -XX:LogFile solution.

Sets the quantity of compiler threads to use for compilation.

This permits code on class route that relies on the usage of setAccessible to break into JDK internals, or to try and do other illegal obtain on customers of lessons in these packages, to work According to earlier releases. This allows both of those static accessibility (for example, by compiled bytecode) and deep reflective accessibility.
