Description
When running the dojo compressor on large inputs, I get strange exceptions.
On my 1.2Mb input, running JDK 1.5.0_10, 32bit on Gentoo linux, I get the following stack trace (I get the same stack trace on Win32 JDK 1.6.0_01):
Exception in thread "main" java.lang.IllegalArgumentException?: out of range index

One user on the compressor documentation page reports the following exception for his 636Kb input file:
