This is what is says on http://www.chemaxon.com/marvin/help/developer/beans/beanfaq.html#question0


Which Java versions are supported by Marvin Beans?


Marvin
Beans requires at least Java 1.4.2. But Java 1.5 or 1.6 is recommended
for Marvin. Sun has already closed support for Java 1.4.2. We plan to
update the minimum Java requirement for Marvin to Java 1.5.


However, trying to use MarvinBeans.jar with Java 1.4 yields the following incompatible-byte-code error that implies that 1.5 is needed:


Exception in thread "main" java.lang.UnsupportedClassVersionError: chemaxon/formats/MolImporter (Unsupported major.minor version 49.0)

Could someone from ChemAxon please update the system requirements as to not take up other people's time.


 


Thank you,

Since Marvin 5.2, the minimum Java requirement is 1.5.


Thanks for the comment, we have updated the documentation.
