Is there a limit to the length of the classpath, or is this just inconvenient?

I am not sure whether there is a limit but it is definitely inconvenient. For example, the command displayed in "ps aux" is truncated. I see something like

Tsz Wo (Nicholas), SZE commented on HADOOP-6368:
------------------------------------------------
One problem is that the ivy path is not consistent among subprojects. The same jar file may exist in different location. e.g. we have
- build/ivy/lib/Hadoop-Core/common/commons-logging-1.0.4.jar
- build/ivy/lib/Hadoop-Hdfs/common/commons-logging-1.0.4.jar
- build/ivy/lib/Hadoop/common/commons-logging-1.0.4.jar
Below is the classpath I got:
