error while using picard 2.1.0

Question

[kirannbishwa01]

I have been using picard for a while and it was working good. I just downloaded a new version of picard 2.1.0. While the previous upgrades worked fine the recent picard does not seem to respond and is giving me error message related to java.

Since the jar files are executable using java I put both version in different folders and tried to run them with the same samples and same commands:

Picard version 1.139:

java -jar /home/everestial007/picard-tools-1.139/picard.jar CleanSam I=SAMPEaligned_MA605readsBWA.sam O=clean_ aligned_MA605readsBWA.sam

works perfectly

Picard version 2.1.0:

java -jar /home/everestial007/picard-tools-2.1.0/picard.jar CleanSam I=SAMPEaligned_MA605readsBWA.sam O=clean_ aligned_Pi2_MA605readsBWA.sam

gives me error message -

I never had this issue before and my hunch is that it may or may not be related with java. But, I am little hesitant to update my java as it may turn out not working for other apps that I am currently running.

Any suggestions appreciated.

As of version 2.0.1 (Nov. 2015) Picard requires Java 1.8 (jdk8u66).
