Tiny-Sandbox¶
Principle¶
The Tiny-Sandbox capability of the Core Engine allows to build a Standalone Application optimized for size. This capability is suitable for environments requiring a small memory footprint.
Installation¶
Tiny-Sandbox is an option disabled by default.
To enable the Tiny-Sandbox capability of the Core Engine, set the property com.microej.runtime.capability
to tiny
in mjvm/mjvm.properties
file.
See the example below:
com.microej.runtime.capability=tiny
Note
Before Architecture 8.1.0, enabling the Tiny-Sandbox capability
was done by setting the property mjvm.standalone.configuration
in the configuration.xml
file as follows:
<property name="mjvm.standalone.configuration" value="tiny"/>
See section Platform Customization for more info on the configuration.xml
file.
Limitations¶
In addition to general Limitations:
- The maximum application code size (classes and methods) cannot exceed
256KB
. This does not include application resources, immutable objects and internal strings which are not limited. - The option SOAR > Debug > Embed all type names has no effect. Only the fully qualified names of types marked as required types are embedded.
- Incompatible with dynamic linkers enabling Address Space Layout Randomization (ASLR).
