Dec/01/18 Change: Oracle has made licensing change for Java starting Jan/01/2019. This change dis-allows commercial use of Java 8 and changes license terms to GPL for the later Java version. As such, SPISim can no longer offer free download of SPISimLite. See Oracle’s announcement links below:

Existing SPILite installation for non-paid customer will be disabled on Dec/31/2018.

Once OpenJDK becomes more mature/stable, SPISim maybe able to offer free SPISimLite again.

Visit SPISimLite product page for more details.
