0048087: OOM compressing JS with certain regexp

DescriptionIf the JavaScript included by ComponentProviders includes certain type of regular expressions, an OOM is thrown when it is tried to be compressed.

Note this OOM is captured and the original contents without compression is returned so this issue has no impact on the functionality.
Steps To Reproduce1. Include this line in any JavaScript: 
  const letsCrash = /^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:.[a-zA-Z0-9-]+)*$/;

2. With no module in development serve the JavaScript containing that line:
ERROR in logs:
    at java.util.Arrays.copyOf(Arrays.java:3745) ~[?:?]
    at java.io.ByteArrayOutputStream.grow(ByteArrayOutputStream.java:120) ~[?:?]
    at java.io.ByteArrayOutputStream.ensureCapacity(ByteArrayOutputStream.java:95) ~[?:?]
    at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:137) ~[?:?]
    at org.openbravo.client.kernel.JSMin.action(JSMin.java:188) ~[classes/:?]
    at org.openbravo.client.kernel.JSMin.jsmin(JSMin.java:295) ~[classes/:?]
    at org.openbravo.client.kernel.JSCompressor.compress(JSCompressor.java:57) [classes/:?]

Alternatively execute regexCompression test from MR [1].

fixed BUG-48087: OOM compressing JS with certain regexp

When trying to compress a JS containing a matching for a single
character which includes the / character followed by the ` character an
OOM was produced. Ie. /[/`]/

This was caused by incorrectly detecting the / chracter inside the
single character matching group as regexp termination instead of as /
single character.

Note that other cases including other matching other quotes agfter /
character would have thrown an UnterminatedStringLiteralException.

This is fixed by taking into account when a regexp is inside a single
character match not to consider / as regexp termination.
