Description
Disable the following assertion in parse1.cpp temporarily, to reduce noise in the testing pipelines while the root cause of its failures is investigated in JDK-8305185:

assert(false) failed: Can't determine return type.

This assertion was added by JDK-8303951 to force the re-evaluation of compilation bailouts. The invariant violation it catches is harmless (other than potentially causing a performance degradation) because it leads to a compilation bailout.
Comments
Yes, I think that's reasonable.

We see the assertion in our jdk23u tests as well . So should this be backported until the "real" issue is fixed?

jdk23u backport request I would like to have the patch in jdk23u as well, because the issue is present there too. The backport is clean and low risk.
