What version of operating system and java do you have?

What flush policy was used for code instrumentation? Do you have any 'clover.db*.1' files?

a Virtual Machine about redhat 4

jdk1.5.0_22 or jdk1.6.0_35 has the same error

The flush policy is directed.

some "clover3_1_8.db18c1kl9vnk2rh_ze_6ae5ye_he9dl0ex.s" files

but the file "clover3_1_8.db6ae5ye_he9co7u5" is nothing on it

export ANT_OPTS="-Xms256m -Xmx2048m"

two weeks ago,the build.xml is run ok ,but now fail.

another computer about windows7 run the build.xml is also ok

a Virtual Machine about linux redhat 4

jdk1.5.0_22 or jdk1.6.0_35 has the same error.

The flush policy is directed.

files :"clover3_1_8.db1*.s" "clover3_1_8.db" "clover3_1_8.db6ae5ye_he9co7u5"

The file "clover3_1_8.db6ae5ye_he9co7u5" is empty.


export ANT_OPTS="-Xms256m -Xmx2048m"

Two weeks ago,the build.xml is run ok ,but now fail.

Could you please create a support ticket at (under the "Clover Support" project)? I'd love to help you troubleshoot the problem, but I will need some log files and build files.

Thank you very much.

I change the build.xml to solve this problem.

<target name="with.clover" description="start clover">


<clover-setup flushpolicy="interval" flushinterval="5000"/>


It may be somethings wrong with the default flush policy.

I see "In the most common unit testing scenarios, the default flush policy will suffice." in

So I use the default flush policy in my unit testing scenarios.

When I change it to interval, I can get clover report.
