Unable to sanitize IBM heap dump

[ycrash]

When I tried to sanitize the IBM heap dump, I got the following error.

java.lang.IllegalArgumentException: Unknown id size: 309358450 at org.apache.commons.lang3.Validate.isTrue(Validate.java:552) at com.paypal.heapdumptool.sanitizer.Pipe.setIdSize(Pipe.java:51) at com.paypal.heapdumptool.sanitizer.HeapDumpSanitizer.sanitize(HeapDumpSanitizer.java:105) at com.paypal.heapdumptool.sanitizer.SanitizeCommandProcessor.sanitize(SanitizeCommandProcessor.java:92) at com.paypal.heapdumptool.sanitizer.SanitizeCommandProcessor.applyPreprocessing(SanitizeCommandProcessor.java:79) at com.paypal.heapdumptool.sanitizer.SanitizeCommandProcessor.process(SanitizeCommandProcessor.java:52) at com.paypal.heapdumptool.cli.CliBootstrap.runCommand(CliBootstrap.java:20) at com.paypal.heapdumptool.cli.CliCommand.call(CliCommand.java:9) at com.paypal.heapdumptool.cli.CliCommand.call(CliCommand.java:5) at picocli.CommandLine.executeUserObject(CommandLine.java:2041) at picocli.CommandLine.access$1500(CommandLine.java:148) at picocli.CommandLine$RunLast.executeUserObjectOfLastSubcommandWithSameParent(CommandLine.java:2461) at picocli.CommandLine$RunLast.handle(CommandLine.java:2453) at picocli.CommandLine$RunLast.handle(CommandLine.java:2415) at picocli.CommandLine$AbstractParseResultHandler.execute(CommandLine.java:2273) at picocli.CommandLine$RunLast.execute(CommandLine.java:2417) at picocli.CommandLine.execute(CommandLine.java:2170) at com.paypal.heapdumptool.Application.main(Application.java:50) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.springframework.boot.loader.MainMethodRunner.run(MainMethodRunner.java:49) at org.springframework.boot.loader.Launcher.launch(Launcher.java:108) at org.springframework.boot.loader.Launcher.launch(Launcher.java:58) at org.springframework.boot.loader.JarLauncher.main(JarLauncher.java:65)

You presumably represent https://ycrash.io company which specializes in heap dump analysis. Given the resources you have, it'd be great if you could contribute code change and open a pull request.

Looking further into it, heap dumps produced by IBM/Eclipse OpenJ9 have totally different format. There is not enough incentive to add support for such heap dumps because of low market share of OpenJ9.
