classes instrumented with -type=block sometimes throw AIOOBE when run

Name: kbR10066 Date: 11/29/2002


Instrumentation (either dynamic or static) of a class may result in unexpected
ArrayIndexOutOfBoundsException when the class is run. To reproduce do the
following:

1. Compile the source
--- Test.java ---
public class Test {
public static void main(String[] args) {
new Dummy();
}
}

class Dummy {}
--- end of Test.java ---

> <JDK1.4>/javac -Xjcov Test.java

2. Run the test under dynamic instrumenter with block coverage only:

> java -cp jcov.jar:. com.sun.tdk.jcov.collect.RunMain -type=block Test
java.lang.ArrayIndexOutOfBoundsException
at Dummy._jcov_X_gather(Test.java)
at Dummy.<init>(Test.java:7)
