Confused by all the recent changes in the Java roadmap? We’ve summarized your Embedded Java options here.
Java’s new, rapid release cadence and the disappearance of free quarterly updates from Oracle for older Java versions have challenged the Embedded Java community as well as ISVs and other organizations that bundle Java with their products.
