  later), the
  VapBinaryStreamToSerializableObjectConverter.objectFrom may
  throw RuntimeException.
  
  
  Caused by: java.lang.RuntimeException: invalid type code: 30

Local fix

• this issue can be avoided with
  "-Dsun.lang.ClassLoader.allowArraySyntax=true"

  ****************************************************************
  When using Java Software Development Kit 8.0.5.5 or later, a
  RuntimeException may be thrown by the
  VapBinaryStreamToSerializableObjectConverter.objectFrom
  method.
  "Caused by: java.lang.RuntimeException: invalid type code: 27
  at
  com.ibm.vap.converters.streams.VapBinaryStreamToSerializableObje
  ctConverter.objectFrom(VapBinaryStreamToSerializableObjectConver
  ter.java:63)"
  

Problem conclusion

• Prior to IBM Java SDK 8.0.5.5, the Bootstrap classloader used
  to allow loading array classes, but, IBM Java SDK 8.0.5.5 and
  later now throws a ´java.lang.ClassNotFoundException´. The
  VapBinaryStreamToSerializableObjectConverter now handles this
  exception instead of throwing a RuntimeException.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.15 and 9.0.0.11.  Please refer to the

Temporary fix

• Use the -Dsun.lang.ClassLoader.allowArraySyntax=true JVM
  argument as a temporary workaround.
