The following tests are failing since JDK-8294960 on PPC64 big endian platforms (Linux and AIX).
On PPC64 little endian platforms they do succeed.

java/lang/invoke/condy/CondyBSMException.java
java/lang/invoke/condy/BootstrapMethodJumboArgsTest.java
java/lang/invoke/condy/CondyBSMInvocation.java
java/lang/invoke/condy/CondyBSMValidationTest.java
java/lang/invoke/condy/CondyInterfaceWithOverpassMethods.java
java/lang/invoke/condy/CondyTypeValidationTest.java
java/lang/invoke/condy/CondyNameValidationTest.java
java/lang/invoke/condy/CondyNestedTest.java
java/lang/invoke/condy/CondyRepeatFailedResolution.java
java/lang/invoke/condy/CondyReturnPrimitiveTest.java
java/lang/invoke/condy/CondyStaticArgumentsTest.java
java/lang/invoke/condy/CondyWithGarbageTest.java
java/lang/invoke/condy/CondyWrongType.java
java/lang/invoke/condy/ConstantBootstrapsTest.java

They fail because of StackOverflowError.

This is the error when running java/lang/invoke/condy/ConstantBootstrapsTest.java with additional arguments -XX:MaxJavaStackTraceDepth=100k -XX:+ShowHiddenFrames
(@run testng/othervm -XX:+UnlockDiagnosticVMOptions -XX:UseBootstrapCallInfo=3 -XX:MaxJavaStackTraceDepth=100k -XX:+ShowHiddenFrames ConstantBootstrapsTest)

The beginning of a new recursion is marked with `Rec` (not easy to see because Jira removes leading whitespace, see also attachment).
