Optional info

• intermittent failure (no):
• New test:
• Part of the excluded Investigate JTreg tests failing against Openj9 Java 11 builds adoptium/aqa-tests#585
• My assumption is that this is currently not suitable for openj9 due to the appearance of sun/hotspot/WhiteBox.registerNatives()

Seems like a problem with the test setup, that the required native library isn't available.

[M-Davies]

Fails with the same error in JDK13-openj9. @build sun.hotspot.WhiteBox is declared at compilation. Is there an alternative to sun/hotspot/WhiteBox that openj9 uses?

[pshipton]

There is no sun/hotspot/WhiteBox equivalent for OpenJ9. If it's a native library built with Hotspot to support testing, that would explain why it doesn't exist for OpenJ9.

[M-Davies]

It seems strange that this test would have been included in openj9 in the first place. Whitebox is indeed a testing API designed for the Hotspot VM so it seems odd that this wasn't flagged up as a permanent exclude earlier.

No matter. Thanks for the reply @pshipton 👍

adoptium/aqa-tests#585 was an original (Very Quick not Scrutinized) pass at permanent excludes... so just to be clear, this test was excluded previously. Now the set in 585 is going through the scrutiny it deserves, now that we have spare bodies to do so.
