java.nio.BufferOverflowException

[Z223I]

I am new to Android and Java. I have been writing C++ since before a commercial compiler was available.

I have downloaded the latest Android ADT for Windows. I was going through a series of tutorials and everything was going fine.

Something must have changed because ALL of the tutorial apps, even the ones that had compiled before, quit compiling and generated a "Unable to execute dex: java.nio.BufferOverflowException. Check the Eclipse log for stack trace." error.

I was able to find the Eclipse/Error log. It reads:

Session Data:
eclipse.buildId=v22.3.0-887826
java.version=1.7.0_45
java.vendor=Oracle Corporation
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US
Framework arguments: -product com.android.ide.eclipse.adt.package.product
Command-line arguments: -os win32 -ws win32 -arch x86_64 -product com.android.ide.eclipse.adt.package.product

Question 1: Is the problem at the top or the bottom of that stack dump?

Question 2: Any suggestions?

By the way, if I create a new project, it compiles ok.

Thanks!
