RFR: 8276687: Remove support for JDK 1.4.1 PerfData shared memory files

2022-10-12 Thread Ioi Lam
We have code in jdk.internal.jvmstat for supporting an ancient version (JDK 1.4.1). There's currently no test case for this code, so it's likely to be further bit-rotten in the future. Let's remove it now. If anyone wants to connect to JDK 1.4.1, they can use tools from JDK 19 or earlier.
