Limitations
The following table lists the limitations of MicroEJ Architectures version 7.14.0 or higher, for both Evaluation and Production usage.
Please consult Architectures Changelog for limitations changes on former versions.
Note
The term unlimited means there is no Architecture specific limitation. However, there may be limitations driven by device memory layout. Please refer to your VEE Port specific documentation to get the memory mapping of MicroEJ Core Engine sections.
