[jira] Created: (HARMONY-2669) [drlvm][jni] Working with charset
ISO-2022-CN crashes DRLVM
[drlvm][jni] Working with charset ISO-2022-CN crashes DRLVM
-----------------------------------------------------------
Key: HARMONY-2669
URL: http://issues.apache.org/jira/browse/HARMONY-2669
Project: Harmony
Issue Type: Bug
Components: Classlib, DRLVM
Environment: Windows XP i686
Reporter: Salikh Zakirov
Attachments: Enc.java
The attached test crashes debug version of DRLVM on a heap pointer validity check on free().
With the following stack:

Running the same test with J9 produces

[jira] Commented: (HARMONY-2669) [classlib][charsets] Working with
charset ISO-2022-CN crashes DRLVM
Posted by "Gregory Shimansky (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-2669?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12489454 ]
Gregory Shimansky commented on HARMONY-2669:
--------------------------------------------
The bug appears to be in this code of Java_com_ibm_icu4jni_converters_NativeConverter_setSubstitutionBytes (see icu4jni, the patched version for memory leaks):
jbyte* u_subChars = (*env)->GetPrimitiveArrayCritical(env,subChars,NULL);
if(u_subChars){
char* mySubChars= (char*)malloc(sizeof(char)*length);
toChars((UChar*)u_subChars,&mySubChars[0],length);
ucnv_setSubstChars(cnv,mySubChars, (char)length,&errorCode);
if(U_FAILURE(errorCode)){
/* !!! */ (*env)->ReleasePrimitiveArrayCritical(env,subChars,mySubChars /* Here should be u_subChars */ ,0); /* !!! */
return errorCode;
}
free(mySubChars);
}
ICU mistakenly passes a pointer to an array allocated in this function. But on windows in debug mode MSVC has some paranoiac checks that heap pointer allocated in one DLL (ICU) cannot be freed in another DLL (DRLVM). So when VM tries to free mySubChars it fails paranoiac MSVC check.
I checked ICU 3.6 and the code is still the same. Probably we could use patched ICUInterface34.dll and report a bug on ICU. I am not sure how many other places in ICU share the same pattern.

[jira] Updated: (HARMONY-2669) [classlib][charsets] Working with

---------------------------------------
Component/s: (was: DRLVM)
Classlib
Summary: [classlib][charsets] Working with charset ISO-2022-CN crashes DRLVM (was: [drlvm][jni] Working with charset ISO-2022-CN crashes DRLVM)
The bug I think is actually in ICU4JNI native code implementation. When it is running on DRLVM in debug mode, it just contains additional runtime checks from MSVC runtime. The stack trace shows that free() is called on an invalid array elements pointer passed by the native code to ReleaseByteArrayElements.
Java stack looks like this:
com/ibm/icu4jni/converters/NativeConverter.setSubstitutionBytes(J[BI)I (NULL:-
2)
com/ibm/icu4jni/charset/CharsetEncoderICU.implReplaceWith([B)V (NULL:-1)
java/nio/charset/CharsetEncoder.replaceWith([B)Ljava/nio/charset/CharsetEncode
r; (CharsetEncoder.java:784)
