  While enabling -Xcheck:jni:all,nowarn,noadvice,nonfatal option,
  customer observe the following message in stderr logs:-
  JVMJNCK023E JNI error detected. Continuing...
  JVMJNCK029E JNI error in GetArrayLength: This function cannot be
  called inside of a critical section
  JVMJNCK077E Error detected in
  sun/awt/image/JPEGImageDecoder.readImage(Ljava/io/InputStream;<O
  SB>B)V
  Also, this may lead to some other unpredictable behavior like
  hang.
  

Local fix

• N/A
  

Problem summary

• The problem is caused while processing the JPEG files where a
  JNI method was called inside a critical section.
  

Problem conclusion

• The JDK has been updated to make the JNI call before acquiring
  the critical section.
  .
  This APAR will be fixed in the following Java Releases:
   8 SR3 FP1 (8.0.3.11)
   7 SR9 FP60 (7.0.9.60)
   7 R1 SR3 FP60 (7.1.3.60)
   6 SR16 FP35 (6.0.16.35)
   6 R1 SR8 FP35 (6.1.8.35)
