Thanks Alan, I used the one that jtreg uses. The complete configuration of JCOV for jtreg is:
``` DEFAULT_JCOV_SRC_TAG=jcov3.0-b07 DEFAULT_JCOV_SRC_ARCHIVE_CHECKSUM=c5c26085750628d58de275b3f50a7409300c0497 DEFAULT_ANT_VERSION=1.10.8 DEFAULT_ANT_ARCHIVE_CHECKSUM=dbe187ce2963f9df8a67de8aaff3b0a437d06978 DEFAULT_ASM_VERSION=8.0 DEFAULT_ASM_JAR_CHECKSUM=d1a17d07c60e9e82c8b31b1d8f9ca98726418db4 DEFAULT_ASM_TREE_JAR_CHECKSUM=7b31ca94da9f57334a5aed79b40f2b88c5ee9f4f DEFAULT_ASM_UTIL_JAR_CHECKSUM=b21996293fd49851ed9017cfde3191e49f77fbd0 DEFAULT_JTHARNESS_SRC_TAG=jt6.0-b13 DEFAULT_JTHARNESS_SRC_ARCHIVE_CHECKSUM=43936b2616476fcac8ee4bd0132e73c015119337 ``` Could you please share from where I can download the JCOV version that you are referring to?
