SUGGESTED FIX java_io_ObjectStreamClass has two instances of jmethodID clinitId = (*env)->GetStaticMethodID(env, clazz, "<clinit>", "()V"); if (clinitId == NULL) { /* error thrown */ jthrowable th = (*env)->ExceptionOccurred(env); if ((*env)->IsInstanceOf(env, th, noSuchMethodErrCl)) { (*env)->ExceptionClear(env); /* normal return */ } return JNI_FALSE; } which should be changed to jmethodID clinitId = (*env)->GetStaticMethodID(env, clazz, "<clinit>", "()V"); if (clinitId == NULL) { /* error thrown */ jthrowable th = (*env)->ExceptionOccurred(env); (*env)->ExceptionClear(env); /* normal return */ if (!(*env)->IsInstanceOf(env, th, noSuchMethodErrCl)) { (*env)->Throw(env, th); } return JNI_FALSE; }

EVALUATION The submitter is correct. ###@###.### 2003-01-15 ###@###.### 2003-01-28 No, he's not. The blanket statement that JNI calls may not be made with exceptions pending is false. The spec says that JNI methods which can throw exceptions must check for them. IsInstanceOf is not one of them. This is not a bug. The suggested fix has been implemented even though it may be desirable to lessen the restrictions on certain JNI calls in the future. ###@###.### 2003-09-08
