It appears that many legacy apps will run in El Capitan. Apple just released
Java for OS X 2015-001, implying that Photoshop CS5 will be OK in 10.11. (That version of PS requires Java 6.) We'll see...
According to Apple,
"Java for OS X 2015-001 installs the legacy Java 6 runtime for OS X 10.11 El Capitan, OS X 10.10 Yosemite, OS X 10.9 Mavericks, OS X 10.8 Mountain Lion, and OS X 10.7 Lion.
"This package is exclusively intended for support of legacy software and installs the same deprecated version of Java 6 included in the 2014-001 and 2013-005 releases."
It would therefore seem to be unnecessary to update to Java for OS X 2015-001 if one has already updated with one or the other of the versions mentioned.
Aside: Unless "deprecated" has assumed a technical sense (ie, jargon), it is wholly wrong/inappropriate in this context.
