Description

Use String.join() or one of the org.apache.commons.lang3.StringUtils.join(..) methods instead. These methods are making explicit use of the StringBuffer class. CdmUtils.concat() can not be optimized by the jit, so for each string item the new String object needs to be extended to new length, which is known to be a performance penalty.

The CdmUtils.concat() methods have been deprecated now.
