<p>In the <a href="https://manual.cytoscape.org/en/stable/Launching_Cytoscape.html#install-java" rel="nofollow noreferrer">installation section of the Cytoscape manual</a>, there is information about the versions of Java that are compatible with Cytoscape:</p>
<blockquote>
<p>Cytoscape requires Java 17.</p>
<ul>
<li><p>We recommend a 64 bit Java Runtime Environment (JRE) such as OpenJDK 17.</p>
</li>
<li><p>While Cytoscape versions prior to v3.2 run on Java 6, Oracle and other JVM suppliers have dropped Java 6 support. Consequently, Cytoscape v3.2 and later don’t support Java 6. With v3.3, we also dropped support for Java 7, and with the release of Cytoscape v3.8 we dropped support for Java 8. With v3.10, we droppped support for Java 11, for the same reason.</p>
