JCOV: type=b option leads to invalid coverage file

Name: kbR10066 Date: 09/18/2001


When 'type=b' option is passed to the Jcov agent, it does not report
any errors and produces invalid coverage data file.

To reproduce, compile the following source file x.java with -Xjcov switch:

> <JDK1.4.0beta-b78>/solsparc/bin/javac -Xjcov x.java

--- x.java ---
public class x {
public static void main(String[] args) {
System.out.println("Hello world!");
}
}
--- end of x.java ---

then run it with Jcov agent enabled:

> <JDK1.4.0beta-b78>/solsparc/bin/java -XX:+EnableJVMPIInstructionStartEvent -Xrunjcov:type=b -cp . x

This will produce java.jcov file with many irrelevant classes containing format errors:

--- java.jcov ---
. . .
CLASS: java/net/ContentHandler [public abstract]
SRCFILE: ContentHandler.java
TIMESTAMP: 0
DATA: b
#kind line position count
METHOD: <init>()V [public]
METHOD: getContent(Ljava/net/URLConnection;[Ljava/lang/Class;)Ljava/lang/Object; [public]
. . .
--- end of java.jcov ---
