It also eliminates the need for TAGS files, browser database (PDB) files,
etc. Once you know the class name, all of the filenames follow from that.

I suspect that the one-to-one correspondence between classes and .class
files is mostly technical (e.g. Java's security model). The one-to-one
correspondence between class files and source files could probably be
relaxed, but at the expense of complicating the IDE and toolchain.

I never saw it as a problem, given that Java is fundamentally class-based:
there are no global variables or functions, only classes.
