Method Detail

verify

public static boolean verify(String jarPath)

Use VM verifier to make sure that supplied jar is correct.

Note: for this API to function, compilation time flag ENABLE_VERIFY_ONLY=true must be specified

Parameters:

jarPath - path to JAR file to verify

Returns:

true if supplied JAR is correct, false otherwise

verify

public static boolean verify(String jarPath,
                             int chunkSize)

Use VM verifier to make sure that supplied jar is correct.

The verification of a JAR is performed in chunks. During verification of a chunk no other isolates can execute. Each chunk consists of one or more class files. The size of a chunk is the total compressed size of JAR entries in the chunk. Verification of a chunk stops when either the size of a chunk exceeds the specified chunkSize or there are no more entries in the JAR. Larger values of chunkSize ensure faster verification of the JAR, but other active isolates will have less chances to execute while the verification is in progress.

This method is multitask-safe, i.e. it can be invoked from multiple tasks at the same time.

The method returns after the whole JAR is verified and the return value indicates if the JAR is correct.

Note: for this API to function, compilation time flag ENABLE_VERIFY_ONLY=true must be specified

Parameters:

jarPath - path to JAR file to verify

chunkSize - size of the JAR file chunk

Returns:

true if supplied JAR is correct, false otherwise

Throws:

IllegalArgumentException - if chunkSize is not positive
