Summary
Bamboo fails to start when upgrading to version 9.2.7 or all subsequent versions within the 9.2.x series
Environment
Bamboo 9.2.7 or all subsequent versions within the 9.2.x series
Bamboo versions 9.3, 9.4 and later are not implicated by this issue
Java 8
Diagnosis
After starting Bamboo 9.2.7 or later for the first time, the following messages appear on the <bamboo-home>/log/atlassian-bamboo.log file:
INFO [main] [JDKFilterConfigurator] Could not set JDK 8 DeserializationFilter.
INFO [main] [DeserializationFilterConfigurator] Could not set a JDK 8 DeserializationFilter. Trying to set JDK 11 DeserializationFilter
fatal bootstrap Could not load bootstrap from environment java.lang.RuntimeException: Cannot set any global DeserializationFilter filter.Cause
Bamboo 9.2.7 and later uses deserialization libraries that require the sun.misc.ObjectInputFilter interface, older JDKs, which don't have that interface implemented, will prevent Bamboo from starting up.
Solution
Update the Java 8 version used by Bamboo to version 8u121 or later
Optionally, customers can upgrade to Java 11; check the following KB article for instructions: How to upgrade the Java version used by Bamboo.
