How To Fix Bamboo Start Errors After Java Upgrade

Author: erics, January 21st, 2020

PROBLEM DEFINITION Bamboo Catalina error found in catalina.out:

-Djava.endorsed.dirs=/volumes/data/bamboo/current/endorsed is not supported. Endorsed standards and standalone APIs
in modular form will be supported via the concept of upgradeable modules.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

-Djava.endorsed.dirs=/volumes/data/bamboo/current/endorsed is not supported. Endorsed standards and standalone APIs

in modular form will be supported via the concept of upgradeable modules.

Error: Could not create the Java Virtual Machine.

Error: A fatal exception has occurred. Program will exit.

SOLUTION SUMMARY Correct by using Java 8 instead. Do it manually using alternatives –set, or interactively using alternatives –config. MANUAL PROCEDURE – two steps, one for java and one for javac

alternatives --set java /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java
alternatives --set javac /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/javac

1 2	alternatives --set java /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java alternatives --set javac /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/javac

INTERACTIVE PROCEDURE – two steps, one for java and one for javac

root@bamboo:/root # alternatives --config javac

There are 3 programs which provide 'javac'.
