Bug in license reading

Aspose.PDF Product Family
1

Aspose PDF for Java (jdk16) has from version 19.9 onwards bug while reading license files.
Result is following code:

Caused by: java.security.SignatureException: Signature decryption error: javax.crypto.BadPaddingException: Invalid PKCS#1 padding: no leading zero!

	at org.springframework.beans.BeanUtils.instantiateClass(BeanUtils.java:148)

This is executed on Windows Server 2008 R2. We use 4 other Aspose modules and none of them, in any version has problems with reading the license file, so something specific happened on this Aspose module from version 19.9->19.10.
