原因
Some random char codes are saved in one of the config files or a corrupted configuration file can cause this error.
ソリューション
Bamboo Server
Check <BAMBOO-HOME>/bamboo.cfg.xml config file and remove all random char codes that appear there. If not sure what should be in that file, install a fresh empty Bamboo instance and compare the config files.
Bamboo Remote agent
Rename or move the existing <BAMBOO-AGENT-HOME>/bamboo-agent.cfg.xml and then start the remote agent.
