[...]Cause
This Java version binary is incompatible with Bamboo 7.2+.
Solution
Upgrade JDK 8 to the latest available version, or to JDK 11 for Bamboo versions 8.0 and higher. For Bamboo 9.4 and later, use JDK 17, and for Bamboo 10.1, you can use either JDK 17 or JDK 21.
JDK 11, 17, 21 and JDK 8u341 use TLS 1.3 by default causing certificate errors when connected to agents, for more details please see the documentation.
