[JENKINS-45937] ArrayIndexOutOfBoundsException when $VARIABLE in project list contains comma

Set an environment variable to PROJECTS=job1,job2

Add Trigger parameterized build on other projects step and set Projects to build to $PROJECTS

When running the job you will get an

The offending code is

					String[] projects = config.getProjects(build.getEnvironment(listener)).split(",");

					String[] vars = config.getProjects().split(",");

					for (int i = 0; i < projects.length; i++) {

if (vars[i].trim().contains("$")) {

One can easily see the arrays will be of different length when an enviorment variable contains the , character.

I don't understand why this logic is needed there though and the commit message only says "Trigger project by using parameters". sshelomentsev ?
