RFR: 8289688: jfr command hangs when it processes invalid file

[Yasumasa Suenaga]

jfr command was in infinite loop when I passed invalid file which are in JFR repository of GraalVM Native Image (I attached the recording file to JBS).

CPU usage was 100% when jfr hanged, and I got following thread stacks:


"main" #1 prio=5 os_prio=0 cpu=10333.35ms elapsed=10.67s tid=0x00007f4994013810 nid=10079 runnable [0x00007f499adfe000]

And also I got following log with `-J-Xlog:"jfr*=info"` - chunk size was 0, and the parser hanged in processing first chunk (id = 0):


$ jfr -J-Xlog:"jfr*=info" print ~/2022_07_04_18_05_11.jfr
[0.353s][info][jfr,system,parser] Chunk: 0

We should abort the process when invalid chunk was detected.
