test dacapo-xalan_0 fails on JDK8 Arm32

test dacapo-xalan_0 in the jdk8 hs extended perf test suite fails on arm32

Latest failure https://ci.adoptopenjdk.net/job/Test_openjdk8_hs_extended.perf_arm_linux/26/tapResults/
I have rerun the test on other arm32 machines, still fails

Start with the JDK8 HotSpot extended performance suite and the dacapo-xalan_0 test, then inspect the linked TAP results and reproduce the failure on an ARM32 machine. Trace the reported Xalan TransformerException and compare results across the other ARM32 machines mentioned. Done means the test no longer fails on the affected ARM32 configurations or the failure is explicitly handled.
