Hi Adam,

I've tested this change on a Linux PPC64 big endian system. Sadly I still get StackOverflowErrors.
I've run only test/jdk/java/lang/invoke/condy/ConstantBootstrapsTest.java. I've experimented with `ThreadStackSize` and `VMThreadStackSize` without success.

When running the test standalone I get the following message:


./jdk/bin/java
-cp testclasses:jtreg_latest/lib/testng-7.3.0.jar:jtreg_latest/lib/jcommander-1.82.jar
-XX:+UnlockDiagnosticVMOptions
-XX:UseBootstrapCallInfo=3
-Xint
org.testng.TestNG
-testclass
ConstantBootstrapsTest
Error occurred during initialization of boot layer
java.lang.StackOverflowError


It's likely not a byte ordering problem since @offamitkumar cannot reproduce the failures on s390x.
