IJ41595: LONG "-CLASSPATH" VALUES OVER 6144 CHARACTERS ARE TRUNCATED ON Z/OS

APAR status

• Closed as program error.

Error description

• Error Message: Exception in thread "main"
  java.lang.NoClassDefFoundError
  .
  Stack Trace:
  .
  When defining a classpath, if the location of a jar file does
  not completely occur in the first 6144 characters the JVM will
  fail with a NoClassDefFoundError while attempting to load
  classes which exist in that jar file.
  

Local fix

Problem summary

• An internal buffer holding the classpath has a fixed size,
  leading to a truncation of any classpath string greater than
  that size.
  

Problem conclusion

• The JVM has been updated to calculate the length of the
  classpath string and allocate a buffer of sufficient size.
