Not really, without rewriting the tests.

This also fails on x86, the exact number of failures varies between runs because of the randomness of deoptimisation.

Here is what I get on three consecutive test runs on x86.

X86: Run1 - 6 failures due to osr_compileable exception

FAILED: compiler/tiered/NonTieredLevelsTest.java
FAILED: compiler/whitebox/ClearMethodStateTest.java
FAILED: compiler/whitebox/DeoptimizeMethodTest.java
FAILED: compiler/whitebox/EnqueueMethodForCompilationTest.java
FAILED: compiler/tiered/TieredLevelsTest.java
FAILED: compiler/whitebox/MakeMethodNotCompilableTest.java

x86: Run2 - 5 failures

FAILED: compiler/tiered/TieredLevelsTest.java
FAILED: compiler/tiered/NonTieredLevelsTest.java
FAILED: compiler/whitebox/DeoptimizeMethodTest.java
FAILED: compiler/whitebox/GetNMethodTest.java
FAILED: compiler/whitebox/MakeMethodNotCompilableTest.java

x86: Run3 - 8 failures

FAILED: compiler/tiered/NonTieredLevelsTest.java
FAILED: compiler/tiered/TieredLevelsTest.java
FAILED: compiler/whitebox/ClearMethodStateTest.java
FAILED: compiler/whitebox/DeoptimizeMethodTest.java
FAILED: compiler/whitebox/GetNMethodTest.java
FAILED: compiler/whitebox/DeoptimizeAllTest.java
FAILED: compiler/whitebox/EnqueueMethodForCompilationTest.java
FAILED: compiler/whitebox/MakeMethodNotCompilableTest.java

The set of tests which fails also varies every time.

I think this will get fixed upstream.
