After using following settings, the error is gone. The problem is version number. 
If we dont give version it will take 1.2.1 and failed in Linux. 
If you put 1.2 it works fine in Linux.

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>findbugs-maven-plugin</artifactId>
<version>1.2</version>
<configuration>
	<findbugsXmlOutput>true</findbugsXmlOutput>
	<findbugsXmlWithMessages>
		true
	</findbugsXmlWithMessages>
	<xmlOutput>true</xmlOutput>
</configuration>
</plugin>

Problem Statement: Java / Oracle Exception

logExceptions, Io exception: The Network Adapter could not establish the connection

Test cases are working fine in dev environment. Same tests are failed in unix environment and caused the above exception.

Solution: In config file database host name is abcd. From Unix environment, it failed to resolve this name to ip address.

Replaced host name with ip address. Now it is working in windows and unix too.
