[tycho-user] JVM Crash during Tycho build

[Aurélien Pupier <aurelien.pupier@xxxxxxxxxxxxxx>]

Hi,

I would like to know if others encounter a JVM crash during Tycho build. It is a JVM bug when a jar is read and write simultaneously. It seems that it exists a workaround only on Oracle VM (-Dsun.zip.disableMemoryMapping=true) In our CI, the crash occurs 3 to 10 times per month.

Does someone else encounter this issue?

If several people are concerned, it might worth to modify algorithm on Tycho side to avoid the issue.

Regards,

just an extract of some lines of the crash report:
