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

Download the program from SourceForge: http://jperfmeter.sourceforge.net/
cd
unzip jperfmeter - 1.4.0.zip
Create a shell wrapper called jperf:
#!/bin/sh
java - classpath jperfmeter . jar : oncrpc . jar com . infineco . Perfmeter $ *
Here is how I invoke jperfmeter using a shell script called perfmon: perfmon script
#!/bin/sh
# perfmon - calls jperfmeter
( cd ~ / jperfmeter - 1.4.0 ; java - classpath jperfmeter . jar : oncrpc . jar com . infineco . Perfmeter $ * ) > / dev / null 2 > & 1 &
HINT: rpc.rstatd and jPerfmeter communicate using RPC via UDP – be sure to open your firewall to allow this.
