Hi all,
I'm having a strange issue where if I compile my class files with
Eclipse ADT, my app works, but if I compile it using javac, I get a
VerifyError. Here's what logcat says:

Method)
Here's the offending method:
public Array2D calcMultiRange(double[] range) {
ArgChecker.isGT(range.length, 0, "range.length");
int numSamples = range.length;
int numLevels = calcNumLevels(numSamples);
double[][] multiRange = new double[numLevels][];
double[] prevRange = null;
for (int level = 0; level < numLevels; level++) {
double[] currRange = new double[numSamples];
if (level == 0) {
for (int i = 0; i < numSamples; i++) {
currRange[i] = range[i];
}
} else {
for (int i = 0; i < numSamples; i++) {
int prevIndex = i * 2;
currRange[i] = calcRangeValue(prevRange[prevIndex],
prevRange[prevIndex + 1]);
}
}
multiRange[level] = currRange;
prevRange = currRange;
numSamples /= 2;
}
return new JavaArray2D(multiRange);
}
Which is triggered by this initializer is another class:
private MipMapStrategy defaultMipMapStrategy =
DefaultMipMapStrategy.MEAN;
Changing to constructor based initialization changes nothing. I also
stubbed out the calcMultiRange() method to return null, and still got
the same error. There are no missing classes as far as I can tell.
Anyway else hit this issue? The workaround (for me) it to have ant/
maven compile using Eclipse or Jikes.
