    java/lang/OutOfMemoryError is thrown
    .
    Stack Trace: N/A
    

Local fix

Problem summary

  • When an application enters JNI and doesn't leave for some time
    and calls NewStringPlatform (or other related functions that use
    character conversion) repeatedly, both the Java Heap and Java
    Stack fill up with char arrays, byte arrays,
    BufferOverflowException, CharToByteConverter etc objects (and in
    their references, in the case of the Java Stack).
    

Problem conclusion

  • NewStringPlatform and related functions have been altered to
    ensure all memory and JNI local refs are freed/deleted once they
    are finished with.
    
    This defect will be fixed in:
    6.0.0 SR9 FP2
    6.0.1 GA FP1
