Hi,
 
I ran code coverage for junit suites in the following environment:
 
OS: Windows 2000
JVM: sun jdk142, sun jdk15, sun jdk16
 
Summary
--------------
I got some errors for suites - lang (java.lang.OutOfMemoryError for all jvms ) and jdbcapi (only on jdk16). Results and errors are given below.
I am planning to rerun code coverage with increased heap size for lang and for jdbcapi errors, I am planning to get latest version of jdk16 and rerun again.
 
Results
