+The jhat tool has been removed. jhat hprof file parser/validator

+com.sun.tools.hat.internal.parser -> jdk.test.lib.hprof.parser
+com.sun.tools.hat.internal.util -> jdk.test.lib.hprof.util

+jhat was added in JDK 6 and its original implementation was from

+There hasn't been much update to jhat tool in the JDK. In addition,
+there are several better heap dump visualizer/analyzer emerged since
