Here is an additional info on the same issue. It seems to be a concurrency
issue. It happens when the same code is executed simultaneously from
different threads. It is inconsistent from build to build, from PC to PC.
Environment: JVM 1.5, WebLogic 10.0, OS Windows XP

java.lang.IndexOutOfBoundsException: Index: 0, Size: 1
	at java.util.ArrayList.RangeCheck(ArrayList.java:546)
	at java.util.ArrayList.get(ArrayList.java:321)
	at
net.sourceforge.cobertura.coveragedata.LineData.getJumpData(LineData.java:316)
	at
net.sourceforge.cobertura.coveragedata.LineData.touchJump(LineData.java:259)
	at
net.sourceforge.cobertura.coveragedata.ClassData.touchJump(ClassData.java:453)

We need it fixed ASAP. It is a great tool. However, I am very sorry to
say, we may move to other tool because of this issue. Our deadlines are too
short.

Thank you,
Vasyl
