dbx verison 1.2.0 failure to start the java bridge

[yannK]

I upgraded the dbx app version 1 to 1.2.0
and the java is pointing to /usr/lib/jvm/java-7-oracle-amd64

but it fails to load and report in jbridge.log

[bwang_splunk · Accepted solution]

DBX 1.2 only support Jre 1.8.

[yannK]

yes, this is the reason:

"Supported versions: DB Connect 1.1.x requires Java 1.6 or 1.7 only. DB Connect 1.2 requires Java 8 only. DB Connect 2.0 requires Java 8 only."
