Yes, in JSR-170 the jcr:like() function is specified to only work on String 
properties. And I think this makes sense, because a like operation on a potentially 
large text which is not tokenized may be quite expensive. you should then rather use 
jcr:contains which also works on fulltext indexed binary properties.

I think this is a reasonable extension that we should consider in jackrabbit.

it is tracked with this issue:
