[midPoint] Connector deployed into icf-connectors raising security exception.

[Prabhakara Rao Doddapaneni]

I created a connector and deployed to icf-connectors folder of midpoint home directory.  When trying to test the connection from resource configuration, it is failing with the following cause:
Caused by: java.lang.SecurityException: Prohibited package name: java.util.concurrent at java.lang.ClassLoader.preDefineClass(ClassLoader.java:662) ~[na:1.8.0_111] at java.lang.ClassLoader.defineClass(ClassLoader.java:761) ~[na:1.8.0_111] at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) ~[na:1.8.0_111] at java.net.URLClassLoader.defineClass(URLClassLoader.java:467) ~[na:1.8.0_111] at java.net.URLClassLoader.access$100(URLClassLoader.java:73) ~[na:1.8.0_111] at java.net.URLClassLoader$1.run(URLClassLoader.java:368) ~[na:1.8.0_111] at java.net.URLClassLoader$1.run(URLClassLoader.java:362) ~[na:1.8.0_111] at java.security.AccessController.doPrivileged(Native Method) ~[na:1.8.0_111] at java.net.URLClassLoader.findClass(URLClassLoader.java:361) ~[na:1.8.0_111] at org.identityconnectors.framework.impl.api.local.BundleClassLoader.loadClass(BundleClassLoader.java:76) ~[connector-framework-internal-1.4.2.18.jar:na] at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[na:1.8.0_111] at org.slf4j.helpers.SubstituteLoggerFactory.<init>(SubstituteLoggerFactory.java:43) ~[slf4j-api-1.7.12.jar:1.7.12] at org.slf4j.LoggerFactory.<clinit>(LoggerFactory.java:75) ~[slf4j-api-1.7.12.jar:1.7.12]
Did anybody get this error before and resolved it?
Any clues are highly appreciated.
