I approve this patch.   I'll create a JBS issue to follow up the test update.

test/jdk/tools/jlink/JLink100Modules.java line 75:

> 73:             for (int j = 0; j < i % 20; j++) {
> 74:                 moduleInfoContent.append("  requires module" + j +

> 75:             }

Do you want to keep this change?   or at least take out the comment since this 
doesn't feed DedupSetBuilder.

Can you add a comment about "the numbers cannot be arbitrarily increased".
