JCompiler: ArrayIndexOutOfBoundsError showing error messages

Compiling (jcompile) the attached program I've got the
below error:

This is the JCompiler shell.
This shell offers four commands:
* "javac [options] files..." -- invokes the javac
compiler (the one chosen in the option pane)
* "compile" -- compiles the current file
* "compilepkg" -- determines basedir of current file
and compiles all outdated files in the basedir tree
* "rebuildpkg" -- determines basedir of current file
tree and recompiles all files in the basedir tree.

JCompiler ready.
