[jdk17] RFR: 8268641: [foreign] assert(allocates2(pc)) failed: not in CodeBuffer memory with ShenandoahGC

[Jie Fu]

Hi all,

The following 4 tests failed with -XX:+UseShenandoahGC on x86 (both release and debug VMs).

java/foreign/stackwalk/TestStackWalk.java
java/foreign/valist/VaListTest.java
java/foreign/TestUpcall.java
java/foreign/StdLibTest.java


The reason is that code buffer size for upcall_stub_linkToNative is too small.
To fix the crash, the size has been increased from 1024 to 2048 (note: 1536 is still not enough).

Thanks.
Best regards,
Jie
